travel on liquid size

Here's the 411 on the TSA's 3-1-1 liquids rule

We've all been there. Waiting in the Transportation Security Administration line only to hear agents call for a "bag check," often because a traveler had a liquid product in their carry-on that's over the allowed limit (or some sort of other prohibited item).

It's a process that can sure slow things down, particularly on the busiest travel days. As you pack for your trip and consider what to put in your carry-on or checked luggage, it's important to consider what the TSA's limits are for liquids and similar products.

Since September 2006, the TSA has gone by the 3-1-1 rule when it comes to those types of products, including items like toothpaste, shampoo, conditioner, mouthwash and lotion -- sunscreen included.

In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container ("3"), all containers must be placed inside one clear quart-size plastic bag ("1") and each passenger is only allowed one plastic bag ("1").

If you meet those requirements, you should get through security without issue. However, if your liquid items are larger than 3.4 ounces each, you'll have to leave them in your checked bag.

There are a few exceptions, though.

The TSA has kept in place a temporary pandemic exception to the rule, allowing up to 12 ounces of liquid hand sanitizer in carry-on baggage.

Part of this exception: The hand sanitizer will have to be screened separately since it's technically over the limit. You'll need to remove it from your bag before it goes through the scanner.

There are also exceptions for larger amounts of medically necessary liquids, gels and aerosols. You can bring those products in larger, "reasonable" quantities, the TSA's website says. However, you must declare those items to security officers at the checkpoint for inspection.

This could, obviously, take a little more time than if you're traveling without those items.

This exception doesn't include sunscreen, despite calls to relax sunscreen restrictions at TSA checkpoints. Like other liquid products, sunscreen bottles over 3.4 ounces must go in your checked luggage.

There are also many liquids you cannot bring with you .

You can bring creamy cheeses, liquid chocolate, liquid coffee, creamy dips and spreads, gravy, honey, hummus, ice cream, jam, jelly, juice, syrup, peanut butter, salad dressing, sauce, salsa, soda, soup and yogurt as long as they are in a container of less than 3.4 ounces according to the TSA .

Related: Should you get TSA PreCheck or Clear — or both?

And yes, you can bring your water bottle with you, even if it weighs more than 3.4 ounces — as long as it's empty. This can also be a great way to save money at the airport, since -- as the TSA points out -- many airports have filling stations for reusable water bottles.

When in doubt, consult the TSA's list of what you can carry through the airport and check with your airline.

The TSA Liquids Rule for Carry-on Bags (3.4 ounces)

Tsa 3-1-1 rule, exceptions to the tsa liquids rule, tsa liquids rule for precheck, does tsa consider makeup a liquid, converting 3.4 oz to ml – how many ml is 3.4 ounces, what does 3.4 oz (100 ml) look like, converting 100 ml to oz – how many oz are in 100 ml, 100 ml to cups, 100ml bottle size – how big is a 100ml bottle, wrapping up: tsa liquids policy, more carry-on content:.

Before you finish packing to head to the airport, always double-check your carry-on bags and make sure you don’t have any bottles or other items that don’t comply with the TSA liquids rule, (known as the 3-1-1 rule).   

By the time the TSA finds that expensive bottle of perfume or lotion in your bag, it’s too late and you’ll have to say goodbye and hand it over to get through security and board your plane on time.  It’s happened to my family many times and could easily have been avoided with a quick check before leaving.

To help make sure this doesn’t happen to you, we’ve created this article that will tell you everything you need to know about the TSA liquids rule, including how much liquid is 100 ml, what are travel-sized bottles, what is considered a liquid, etc. Basically, all the stuff that could get confiscated when making your way through airport security.

What’s the TSA Liquids Rule?

The TSA liquids rule states that you can bring a quart-sized bag of liquids, aerosols, creams, gels, and pastes in your carry-on bag and through the airport security checkpoint. However, you are limited to containers that are travel sized and contain less than 3.4 ounces (100 milliliters) per item.

Items that are in packages or bottles larger than 100 milliliters (or 3.4 ounces) will have to go in your checked luggage .  In addition to larger liquids, any liquid that is more than 3.4 oz or 100 ml and is not contained in a secure, tamper-proof bag must be packed in your checked luggage.

Each liquid must be in a 3.4-ounce or less container (“3”), all containers must be placed inside one clear quart-sized plastic bag (“1”), and each passenger is only allowed one plastic bag (“1”).

There are 2 exceptions to the TSA 3-1-1 Liquids Rule

• Medications, and
• Infant/Child nourishment

Medications larger than 100ml

TSA allows larger-sized packages of medical liquids, gels, and aerosols in your carry-on. This also includes medical accessories such as freezer bags, pumps, syringes, etc. These items do not have to be in a plastic zip lock bag, but you will have to declare these items to TSA officers at the checkpoint prior to inspection.

Here’s a video that provides all the details you need about traveling with medication.

Formula, Breast Milk, and Juice

Formula, breast milk, and juice for infants and toddlers are allowed through the security checkpoint. These can be in quantities greater than 3.4 ounces or 100 milliliters and are allowed in carry-on baggage.

Similar to medications, just inform the TSA officer of what you have and remove the items from your carry-on bag so they can be screened separately from the rest of your belongings.

Ice packs, freezer bags, frozen gel packs, and other accessories required to cool formula and breast milk are allowed in your carry-on bag.

The TSA PreCheck Program allows registered travelers the ability to go through expedited screening lines at over 200 participating U.S. airports with over 80 participating airlines. Once you are approved in the program you don’t need to remove your 3-1-1 liquids from your bag.

Actually, you can avoid removing any of the following items during the screening process:

• 3-1-1 compliant bag
• Light jacket/Sport coat/outerwear
• Laptop / iPad from bag

To apply for PreCheck, go to tsa.gov/precheck . From here you can enroll and make an appointment online or walk in at any one of over 380 enrollment centers . It can take up to 30 days to obtain a TSA PreCheck known traveler number.

What does TSA consider a liquid?

According to TSA guidelines, any substance that is free-flowing or viscous is considered a liquid. This includes liquids, aerosols, pastes, creams, and gels.

According to the TSA, “Makeup in a solid or powder form is allowed in carry-on and checked bags with no quantity or size limitations. However, when packed in carry-on bags, makeup in a liquid, lotion, gel, paste, or creamy form, must be in containers that are 3.4 ounces or less. You can take as many travel-sized liquids as you can comfortably fit into one quart-sized, zip-top bag.”

When it comes to makeup, the following are some examples of liquid cosmetics:

• Nail polish,
• Moisturizers,
• Foundation,
• Mascara, etc.

How much is 3.4 oz?

Now that you understand the basic concepts of the TSA liquid rule, it may help to have an idea of what constitutes 3.4 oz or 100 ml, since most people don’t naturally know how big a 3.4-ounce container or a 100 ml bottle is.

So if you’re wondering exactly how much is 3.4 oz or how big is a 100 ml bottle, we will walk through that for you here.

3.4 ounces (oz) converts to 96.388 milliliters (ml). For purposes of simplicity, the TSA rounds this up to 100 ml

Most of the toiletries you would bring on a trip come in travel-sized packages that can be bought at any drug store or grocery store. These travel-sized items are typically 3 ounces (90 ml) and generally provide enough lotion, shampoo, or toothpaste for a 5-day trip. If you’ll be traveling longer, you may need to stock up on a couple of extra bottles or plan on purchasing more upon arrival at your destination.

100 milliliters (ml) converts to 3.3814 ounces (oz). For purposes of simplicity, the TSA rounds this up to 100 ml

100 milliliters (ml) converts to .422675 cups, so it’s just under 1/2 cup.

A 100 ml bottle is fairly small. To give you a visual, look at the image below that shows a 500 ml water bottle vs. a 100 ml spray bottle. The 100 ml bottle is about 3 inches tall and the water bottle is about 8 inches tall.

Hopefully, this guide will give you a better idea of what the TSA considers a liquid and what size they will let you bring on your carry-on. Knowing this information in advance can save a lot of headaches at the airport!

Everything You Need to Know About the TSA’s Liquid Limit

The tsa allows liquids under 3.4 ounces in your carry-on—but what’s considered a “liquid” isn’t always obvious..

Whether you’re a carry-on-only kind of person or not , knowing the Transportation Security Administration’s (TSA) liquid limits is essential for anyone who travels by plane in the United States. Yet understanding which of your toiletries, foods, and other items even count as “liquid”—let alone how best to pack them—can get confusing. Use this guide to understand the TSA’s rules and restrictions about liquids, common exceptions, and tips to help ensure your next airport security screening goes smoothly.

What is the TSA liquid limit?

The TSA’s liquid limit for carry-ons—known as the 3-1-1 rule—allows travelers to pack liquids, aerosols, gels, creams, and pastes under 3.4 ounces (100 milliliters) in their carry-on bags. Passengers are allowed up to one quart-sized bag per person , or roughly nine 3.4-ounce containers in a single quart-sized bag. Anything more will have to go in a checked bag or risk being tossed out.

If your liquids are stored in containers larger than 3.4 ounces, even if there’s only 3.4 ounces left inside the bottle, you can’t bring them through security.

Completely empty bottles, such as your reusable water bottle , are allowed through the TSA checkpoint since (spoiler alert!) they don’t contain any liquids at that moment.

Which toiletries TSA allows in your carry-on

The TSA allows all of the following common toiletries in your carry-on only in containers that are 3.4 ounces or less:

• Shampoos and conditioners
• Lotions and sunscreen
• Gel hair products

In other words: yes, you can bring toothpaste, deodorant, and sunscreen through TSA checkpoints but only if they are in travel-sized containers.

Powders and powder-like substances, including baby powder and some makeup items, aren’t restricted in your carry-on bag. But if you’re carrying more than 12 ounces (350 milliliters) of a powder, you’ll need to place it in a separate bin for X-ray screening, and it may be subject to additional screening—so it’s a good idea to budget an extra few minutes at the security checkpoint if you think this might happen.

Tips for packing your toiletries in your carry-on

To comply with TSA regulations, invest in small, reusable toiletry bottles, like these capsules by Cadence.

Especially if you don’t have TSA PreCheck , it’s helpful to pack all of your toiletries in a quart-sized (or smaller) clear plastic toiletry bag for screening. Although improved airport technology means that far fewer air passengers (both in PreCheck and non-PreCheck lines) will have to take their liquids out out of their carry-on, it’s still helpful to have all of your liquids in one bag just in case you get pulled aside for additional screening. For an upgrade from that large Ziplock, we recommend the standard-sized Clarity Jetset Case from Truffle ($88), which has a clear window panel and is comparable in size to a quart-sized bag.

Since toothpaste is considered a liquid, paste, or gel by the TSA, most of us toss those tiny one-ounce tubes in our carry-on bags. However, if you want to ditch the hard-to-recycle packaging, consider toothpaste tablets, an ecofriendly alternative that’s not subject to the 3-1-1 rule. We like Humankind’s fluoride toothpaste tablets ($12), which resemble small mints and turn to paste when you crush them between your teeth. Matador has also recently released a reusable toothpaste tube ($10), which you can fill (and refill) with your regular toothpaste.

For travel toiletries that are easy to rebottle (like shampoo or body wash), consider investing in reusable bottles or containers so you can always keep your preferred brand on hand. Some of our favorite TSA-approved toiletry bottles include:

Buy Now: GoToob three-pack of 3.4-ounce bottles, $30, rei.com

These easy-to-fill, leakproof silicone tubes are ideal for shampoos, conditioners, lotions, and body washes. GoToob’s line comes in a variety of sizes, ranging from 1.7 to 6 ounces, and are easy to clean between refills.

Matador FlatPack

Buy Now: $13 for one or $35 for three, matadorup.com

Each three-ounce, TSA-approved bottle is made from a durable, waterproof, nylon-based fabric. Like GoToob, they’re leakproof and easy to fill, but thanks to their flexible, fabric-like design, they will shrink to their contents, taking up less space in your pack. >> Read the full review of the Matador FlatPack

The refillable travel containers by Cadence are small, leakproof “capsules” that click together with magnets. At 0.56 ounces, they’re best for makeup and toiletries you don’t need much of—like a weekend’s worth of shampoo or a week of that under eye cream you only need a dab of.

Foods are subject to liquid limits

The TSA’s 3-1-1 rule applies to food too, meaning you’ll need to make sure any foods that count as liquids, gels, or pastes (like yogurt, peanut butter, pâté, jams, or that tasty pimento cheese spread you tried to bring home from Charleston) are less than 3.4 ounces or packed in your checked bag. There are some exceptions, like frozen foods and juice for babies, and the TSA’s website is the best resource to check for specific items.

Exceptions to TSA’s liquids rule: Full-sized liquids that you can bring through security

The TSA has several important exemptions to its liquids rule. You’re allowed to bring full-sized bottles of the following:

Hand sanitizer: Due to the coronavirus pandemic, the TSA currently allows travelers to bring up to 12 ounces of hand sanitizer in their carry-on bags. These will be screened separately.

Medication: You’re allowed to bring medically necessary liquids, aerosols, and gels through security. This also includes the ice or gel packs you may need to keep your medications cool. You are not required to store these items in a plastic, resealable bag, but you should remove them from your luggage and let the TSA officer know what you’ve packed.

Baby formula and breast milk: Like medication, you can bring freezer packs to keep these items cool, and you should remove them from your luggage and notify an agent when you go through security. More baby-related exceptions? Gel or liquid-filled teethers and canned or jarred baby food.

Of course, the final decision on whether an item is allowed through the checkpoint rests with the TSA officer.

If you’re ever unsure about a specific item, the TSA’s website has a handy, searchable list of prohibited and allowed items worth checking before you travel. You can also now text the TSA with your questions.

TSA Liquid Rules Ultimate Guide (3-1-1 Explained) [2023]

Bringing your liquids through airport security is not always as straightforward as you might think.

There are several rules that apply when bringing your liquids through airport security checkpoints and, yes, many are obvious to those of us blessed with a shred of common sense.

But in some cases there are some less obvious restrictions that could apply to your liquids.

And when you start talking about things like baby essentials, medications, and liquids like alcohol, there are many lesser-known rules and exceptions that come into play.

Violating these rules can sometimes mean slowing down the flow of the screening checkpoint (something we all should want to avoid) but in other cases it could mean violating the law and you basically becoming an airport criminal.

And nobody wants that.

So it’s a good idea to get acquainted with how these rules work and in this article, I’ll give you a detailed breakdown of the 3-1-1 rule and also talk about the many different types of exceptions and additional rules that apply to different types of liquids such as medications and alcohol.

What is the TSA Liquids “3-1-1 Rule?”

The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 liquid ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag.

Where does the 3-1-1 come from?

It’s just an easy way to memorize the different requirements that make up the rule and I’ll hit on those below.

3.4 fluid ounces or (100 mL)

The “three” indicates that your liquids must be contained within a container no larger than 3.4 fluid ounces or (100 ml).

(TSA uses 3.4 ounces because it’s easier to remember but really  100 ml comes out to 3.3814 fluid ounces. )

One of the biggest things that people get confused about is that the 3.4 ounce requirement applies to the size of the container and not the liquid within the container.

So let’s say that you have a 6 ounce container with only 2 ounces of fluid inside.

You may think that because you have under 3.4 fluid ounces of liquid, you are good to go but because your container is larger than 3.4 ounces, you cannot bring that through TSA.

The other big thing to know is that this refers to fluid ounces which relates to volume and is very different from ounces used for weight.

Some products like honey could weigh 4 ounces but still fit inside of a 3.4 fluid ounce container. It helps to know how to convert ounces/grams to fluid ounces .

1 quart-sized resealable bag

The first “one” means that your liquids must fit within 1 quart-sized resealable bag. Typically, this will be a clear Ziploc bag which just makes things easy for everybody.

The key thing to note here is that the containers must fit “comfortably” inside this resealable bag.

What does “comfortably” mean?

It basically just means that the bag is not bursting at the seams. (Think about how a pair of jeans should fit when you’re being honest with yourself about your waist size.)

If you are not able to easily reseal your bag, then your contents may not be fitting comfortably inside.

In such a scenario, it’s possible that a TSA agent could ask you to throw something out in order to allow your bag to comply with the rules.

In my personal experience, I have not seen a lot of TSA agents enforce the “comfortable” requirement very strictly but if you have bottles poking out of your liquids bag, I could see that being an issue.

1 quart size bag per person

The last requirement is that you are allowed 1 quart size bag per person.

The easiest way to comply with this is to simply separate your liquids bag from your carry-on and have one liquids bag in your bin when going through security.

Otherwise, it could look like you are trying to bring through two bags of liquids.

The best packing tip I have for this is to keep your liquids bag at the top of your carry-on so that you can easily retrieve it.

There’s nothing worse than scrambling to find that liquids bag while trying to get ready to go through a screening checkpoint.

TSA Pre-Check liquids rule

TSA Pre-Check allows you to bypass the main security line and pass through a screening line that is usually much shorter and quicker. This also means avoiding the full body scanner in many cases. It basically makes you a VIP when it comes to airport security checkpoints.

If you have TSA Pre-Check , you can take advantage of several benefits including things like:

• Shoes can stay on
• Belt can stay on
• Light jackets can stay on
• Laptops allowed to stay in bag
• Liquids (3-1-1) can stay in bag

That last perk is the most relevant to the liquids rule as you will not have to remove your liquids bag and place them in one of the bins when going through security. You can simply leave them in your carry-on and pass through the metal detector without any issue.

I highly recommend that you look into getting Pre-Check in order to expedite your security screening. It will only cost $78 for five years and all you have to do is pass a background check. You can also get it if you are approved for Global Entry ( read how to get approved here ).

New hand sanitizer liquids rule

Due to the ongoing threat of coronavirus and the potential threat of spreading germs throughout airports and aircraft, TSA recently implemented a change with respect to hand sanitizer.

Passengers will now be allowed to bring one hand sanitizer bottle up to 12 ounces. These larger bottles will be screened separately so just be aware that it could add some extra time.

What exactly is a “liquid?”

In some cases, what constitutes a liquid will be very clear.

For example, it’s pretty much common sense that water inside of a water bottle is a liquid. The same applies for cologne, mouthwash, etc.

But liquids also can include less-obvious forms like aerosols, gels, creams, or pastes.

This means that several common items you would be bringing along for your trip could be considered a liquid like: toothpaste , lotion , sunscreen, shaving cream, shampoo , conditioner, and others.

You can find travel-sized products for most of these so it’s usually pretty easy to bring along items that comply with the TSA liquids rule.

Other items

You need to be mindful of other items that could be considered liquids like deodorant . For example, the following types of deodorants will be subject to the 3-1-1 rule:

• and Roll-On deodorants

Prohibited items

Just because you have something like an aerosol and it is in a container no larger than 3.4 ounces, that does not mean that you can bring it as a carry-on.

There are quite a few prohibited items like aerosol insecticide, bear spray, etc. that are not allowed as carry-ons. In fact, some of those items may not even be allowed on the plane at all. This is a good place to search if you are in doubt about whether or not you can bring a particular item.

Be aware that some items like hairspray may even have size restrictions when packed in your checked baggage.

Foods can also be liquids

One aspect of the TSA liquids rule that throws a lot of people off is that they forget many foods also qualify as liquids.

Here is a non-exhaustive list of food items that will fall under the liquids rule:

• Liquid chocolate
• Creamy dips and spreads
• Mashed fruits such as applesauce
• Jam and jelly
• Maple syrup
• Oils and vinegars
• Peanut butter
• Wet pet food
• Salad dressing
• Salsa and sauces

Basically anything that is usually poured, scooped, squeezed, slurped, or mashed will be considered a liquid for TSA purposes.

If your food is solid on the other hand , chances are you can bring it through.

TSA rules for liquid medications

The liquids rule provides exceptions for medical supplies and medications .

TSA allows larger amounts of medically necessary liquids, gels, and aerosols in “reasonable quantities” than your 3-1-1 allowance.

You do not have to have a prescription for these items but keep in mind that you need to comply with state laws regarding prescriptions and controlled substances.

This leaves two questions often to be asked and answered.

The first is what is considered “medically necessary?”

For example, is contact lens solution medically necessary?

It seems the answer to that is probably yes given the TSA states, they allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip” on the page regarding contact lenses.

So if in doubt check the website and then inquire with AskTSA if you still don’t know.

The second question is what is considered a “reasonable quantity?”

What is deemed as a reasonable quantity is a subjective determination.

According to the TSA, you should bring what’s necessary for the duration of your trip (e.g., seven days) plus a day or two just in case things get delayed or canceled.

If you stick to what you think will be necessary for the duration of your trip, I don’t think you will often run into trouble. But if you’re bringing a six month supply of medication on a four day getaway, that’s when you might start to run into trouble if questioned.

TSA states that you must declare them to TSA officers at the checkpoint for inspection.

You also want to remove these from your carry-on so that they can be screened separately from your belongings. (You do not have to put your liquid medication in a plastic Ziploc bag.)

Just be aware that if one of your liquid items declared as medically necessary sets off the alarm, it may require additional screening and may not be allowed.

Baby essentials

You are allowed to bring formula, breastmilk, and juice for infants or toddlers in “reasonable quantities” through airport security. According to the TSA, reasonable quantities for baby essentials typically means the duration of the flight.

When bringing these items through security, be sure to separate these from your carry-on bag so that they can be screened separately from the rest of your items.

If you are carrying liquids in excess of 3.4 ounces, you are advised to inform the TSA officer at the beginning of the screening process that you have excess liquids. You can do this when you are unloading your items into the bin.

In many cases, excess liquids will be screened by x-ray.

It’s also possible that an officer may ask you to open up the container and potentially even transfer a small quantity of the liquid for testing.

If you are worried about the effects of an x-ray machine on your liquids, The Food and Drug Administration states that there are no known adverse effects from eating food, drinking beverages and using medicine screened by X-ray.

If that is not good enough assurance for you, you can ask to avoid the x-ray machine.

Additional steps may be able to be taken to clear the liquid but the traveler will likely have to undergo additional screening procedures which could include a pat down and a thorough screening of all of your carry-on property.

You will also be allowed to bring along ice packs, freezer packs, frozen gel packs and other accessories required to cool formula, breast milk and juice.

If these are in a partially frozen state or perhaps appear like a slushy they will be subject to the same screening as described above.

Other permitted baby items include gel or liquid-filled teethers, canned, jarred and processed baby food.

Just always be aware that these items may have to undergo additional screening.

TSA liquid rules for alcohol

Bringing alcohol through TSA presents a number of different challenges.

First, your alcohol in most cases will have to comply with the liquids 3-1-1 rule. This means that you won’t be able to bring in regular bottles of liquor or beer.

It is possible to find small bottles that are under 3.4 ounces (mini-liquor bottles are often around 1.7 ounces, so this means that they are small enough to be brought on the plane as a liquid).

But contrary to what many people think, it’s also permitted to bring your own alcohol in one of your own containers.

The catch is that there are specific restrictions about what type of alcohol is allowed on board and that can be allowed as a carry-on. You really need to make sure that you are abiding by these rules because you could be violating federal law otherwise.

The first regulation to know is that alcohol beverages with an alcoholic percentage above 70% (140 proof) is never allowed on the plane . In fact, alcohol with such a high alcohol percentage is considered a hazardous material.

If the alcohol content is above 24% but not above 70% then the alcoholic beverage must be in its retail packaging. A lot of popular alcoholic beverages for within this range. Here are some  ranges  for the alcoholic content of some common beverages:

Alcohol Percentage Content

• Vodka | ABV: 40-95%
• Gin | ABV: 36-50%
• Rum | ABV: 36-50%
• Whiskey | ABV: 36-50%
• Tequila | ABV: 50-51%
• Liqueurs | ABV: 15%
• Fortified Wine | ABV: 16-24%
• Unfortified Wine | ABV: 14-16%
• Beer | ABV: 4-8%
• Malt Beverage | ABV: 15%

And finally, one of the most important things to remember is that you are not allowed to serve yourself your own alcohol when flying.

Instead, you must request a flight attendant to serve you the alcohol or else you will be violating FAA regulations. Some flight attendants will happily serve you your own beverage but others will not be so inclined.

If you purchased alcohol at duty free store, different rules apply in that scenario. Basically, you can bring your duty free alcohol through TSA security but you have to comply with three separate requirements:

• The duty free liquids were purchased internationally and you are traveling to the United States with a connecting flight.
• The liquids are packed in a transparent, secure, tamper-evident bag by the retailer and do not show signs of tampering when presented to TSA for screening.
• The original receipt for the liquids is present and the purchase was made within 48 hours.

Checked baggage liquid rules

Many times, you can simply place your liquids in your checked baggage and not have to worry about that pesky 3-1-1 rule.

This is usually the way to go on longer trips when you might be bringing large quantities of things like shampoo or shaving cream.

But as mentioned above, you still need to make sure that the type of liquid is allowed on a plane. Certain materials may be considered hazardous and you could be violating the law by bringing those on board.

If you are loading up your checked baggage with a bunch of liquids, make sure that you double bag if there is potential for the liquids to spill!

TSA Liquid Rules FAQ

The TSA 3-1-1 rule does not apply to checked baggage. However, there are some restrictions on what liquids can be transported in your checked baggage. There may also be limitations on the quantity of liquids when it comes to importing large quantities of things like alcohol. At some point, you might have to obtain a license for certain goods.

TSA definitely enforces the liquids rule and I would recommend not trying to circumvent the rule. It’s possible that an agent may be more lenient than another in certain circumstances but I would always assume that an agent will be enforcing strictly so that I don’t run into any unexpected issues.

TSA has the rules in order to detect potential explosives and other harmful materials that exist in liquid state.

The same liquid rules apply for both domestic flights and international flights. One difference that you might encounter is when you purchase duty free goods before an international flight. See the duty-free section above for more details. Also, when flying internationally it is recommended that you get to the airport extra early. It is possible that you could get hit with SSSS and be forced to undergo a heightened security screening, so always plan out extra time.

While you might view your makeup as special, there are no special rules for your makeup when it comes to TSA. They must abide by the same 3-1-1 rule explained above. Read more about makeup rules here.

No, you do not have to take out your liquids if you have TSA Pre-Check.

The same TSA liquids rule will apply to all airlines. So if you’re flying American or Delta, the rules will be the same as if you were flying Southwest or United. With that said, some airlines do have some differences in how they handle acceptable baggage so you should make sure to read up on the latest baggage policies for the airlines.

If you are traveling from an “international last-point-of-departure” to the U.S ., powder-based substances in carry-on baggage greater than 350mL or 12 oz. may require additional screening. If your substance is over 12 ounces and cannot be cleared it will not be allowed onto the aircraft cabin. TSA recommends that you transport powders in your checked baggage.

TSA has several rules you need to follow when it comes to drinking liquids through airport security. The most well-known is the 3-1-1 rule but there are other considerations you need to think about like foods that might trigger the rule and exceptions for medical and baby essentials. In the end, try to be as reasonable as possible with what you are bringing through and you will run into few problems.

Carry-On Liquid Success: Packing Tips & Must-Have Items

Packing carry-on liquids can be challenging. This guide simplifies the process, ensuring you fit essential toiletries in a one-quart bag. Master the art of selecting and packing your carry-on toiletries, and travel lighter with confidence.

Key Takeaways: Packing Toiletries for Carry-On Luggage

• Follow the TSA 3-1-1 Liquids Rule: Travelers can bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in their carry-on, with each item being 3.4 ounces (100 milliliters) or less.
• Choose the Right Bag: A clear bag, no larger than one quart, is the limit for taking on the plane. A 1-quart Ziploc bag is commonly used.
• Minimize & Optimize Toiletries: Focus on packing only essentials and consider using solid alternatives or utilizing your hotel’s amenities to save space in your liquids bag.

The TSA 3-1-1 Liquids Rule

According to the United States Transportation Security Administration (TSA) , “You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item. Placing these items in the small bag and separating from your carry-on baggage facilitates the screening process. Pack items that are in containers larger than 3.4 ounces or 100 milliliters in checked baggage.

Any liquid, aerosol, gel, cream or paste that alarms during screening will require additional screening.”

What kind of bag should I use to pack toiletries in my carry-on luggage? 

For packing toiletries in a carry-on, use a clear bag no larger than one quart. While many “TSA-approved” bags are available online and in stores, some may seem larger than the limit. To avoid potential issues at security, a 1-quart Ziploc bag is a safe choice.

PRO TIP: Consider getting TSA Pre-check  or Global Entry  (which comes with TSA Pre-check eligibility) so that you can go through security without pulling your liquids bag out of your carry-on luggage.

Tips for packing liquids in carry-on luggage 

Packing all liquid toiletries in a quart bag can be tricky, but with the right strategies, it’s feasible. Here are tips to optimize liquid packing in your carry-on bag .

Cut your skin care regimen down to just the essentials 

Cleanser, toner/liquid exfoliator, facial moisturizer. When packing carry-on liquids, that’s all you need throughout your trip unless you’re traveling for longer than a week. If you have room in your liquids bag after you’ve put in everything else that you need to take, then that’s the time to add in things like spot treatments on overnight masks. 

To trim your skin care liquids even further, use facial cleansing cloths instead of packing liquid, gel or cream cleanser, or face wash. I never travel without these dry cloths that I buy on Amazon and activate with water . That way I can travel with the exact amount I need. They never dry out like the moist towelette ones. 

Tip: use a digital and editable packing list to stay organized and make quick adjustments to your list as you pack for your trip.

Cut your hair care regimen down to the bare essentials 

Only take what you absolutely need to care for your hair on your trip. For you, that might be just shampoo and hairspray.  

If you’re staying in a hotel, you can minimize the toiletries you pack in your carry-on by using the products the hotel provides. Or try a shampoo bar like this one and leave shampoo out of your liquid toiletries bag altogether. 

Use your trip to use up the last of your toiletries 

I love to set aside my last bit of eyeliner or a sample of a skin care product for a specific trip coming up. Then I take those with me on my trip and just throw them out before I come home. 

When you travel carry-on only, every bit of space you make for yourself (especially on a return trip when you might have souvenirs to bring back) can help. 

Replace as many liquid toiletries as you can with solids (or powders that travel well) 

There are a lot of liquid toiletries that you can replace with solid-form versions like solid deodorants, solid shampoos, etc. They don’t need to be packed in your 1-quart liquids bag, which will free up space for you. 

• This is my favorite solid sunscreen stick.  
• You can try this popular solid shampoo bar . 
• You can also get solid conditioner bars like this one . 
• You can even buy solid body lotion to help keep you moisturized while you travel. 
• If it works for you, instead of liquid foundation and concealer, use mineral makeup like this one .  

You’ll save so much space in your carry-on liquids bag.

Share toiletry space with your travel partner  

If you have a travel partner who uses very little in the way of liquid toiletries use him or her as your mule to get a few extra things on the plane. My husband’s liquids bag holds shampoo, toothpaste, and antibacterial ointment. That’s it. So, he usually also takes my shampoo and we share the toothpaste. Now that’s love!  

Buy toiletries at your destination

If you’re going to be traveling long-term you might opt to wait until you reach your destination to purchase some toiletries or over-the-counter liquid medications. 

For example, if you’re planning to spend several weeks in one place (or road-tripping at your destination) you could wait until you arrive to purchase things like shampoo, toothpaste, or sunscreen that you know you will use daily (or multiple times per day).

Toiletries and travel size liquids packing list ideas for carry-on travel

Use this list as a starting place for packing toiletries when traveling carry-on only. You can easily customize it for your own needs and how you like to travel. I like to minimize my toiletries as much as possible and go low maintenance for hair and makeup on my travels.

  Keep track of everything you’re packing with these blank printable packing lists .

You can purchase travel sizes of your favorite products or get some reusable travel-sized containers of various sizes so that you can just take with you a bit of your full-size products from home.

• This “Amazon’s Choice” set comes with many different kinds of containers in different sizes.
• These bottles are also really popular on Amazon.

Skincare products 

• Cleanse with these dry cloths you activate with water. They’re perfect for traveling light. 
• I swear by this day moisturizer with SPF 30. 
• And I never travel without my travel-size bottle of this liquid exfoliant . 

Hair care products 

• Try this solid shampoo bar , so you don’t have to pack it in your liquids bag. 
• This solid conditioner on Amazon gets great reviews. 
• I also usually take a small hairspray with me. I pick up travel-size versions of my favorites at the drug store.

Makeup 

Face makeup .

• I like to travel with a long-lasting concealer or foundation/concealer combo. This concealer is my favorite .
• I also like this “foundcealer.”   
• To cut down on the quantity of liquids you pack in your carry-on, you might want to try a powder mineral foundation like this one . 

Eye makeup 

• I prefer to keep it simple here. I like to pack a good affordable eyebrow pencil with a clear eyebrow gel like this one . 
• Then perhaps try an eyeliner like this one . 
• A good tubing mascara like this one will help prevent smudges. 
• If taking an eyeshadow, consider using a retractable eyeshadow stick. It’s less likely to break up during travel like a traditional powder eyeshadow. 
• Keep it simple with a flattering lip gloss like this . 
• Or perhaps even just use lip balm. I never travel without it, especially on those long, dry flights. 

Miscellaneous toiletries and liquids 

• Travel is the perfect excuse to use up those little toothpaste and floss samples you get from your regular dental checkups. 
• And we never travel without this little item to help remove stains, since at least one of us (me) is a pretty messy eater. 

Packing carry-on liquids FAQs

The TSA 3-1-1 liquids rule can be confusing when it comes to which specific items apply and which don’t. It’s important to remember and follow the TSA liquid rules for everyone’s safety and so you can get through the checkpoint without delay.

What is the 3-1-1 rule for flying with liquids?

The 3-1-1 rule refers to the TSA’s regulation that allows passengers to bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in their carry-on bag and through the security checkpoint. Each container within the bag must be 3.4 oz. (100 milliliters) or less.

Can I use any bag for my carry-on liquids?

While there are many “TSA-approved” clear toiletry bag options available, it’s recommended to use a clear bag no larger than one quart to avoid any discrepancies at security checkpoints. A 1-quart Ziploc bag is a commonly used and reliable option.

Are there any exceptions to the 3-1-1 rule for carry-on liquids?

Yes, there are exceptions to the 3-1-1 rule for carry-on liquids. These exemptions include medications and nourishment for babies and toddlers such as breast milk and formula.

Can I bring toiletries in my carry-on? 

Yes, you can bring toiletries in your carry-on. But you’ll need to take a little care with how you pack liquid toiletries for your flight. Follow the TSA 3-1-1 liquids rule for any liquids, gels, or pastes that you pack. Then you’ll sail through security with no problem.

Can I bring mascara in my carry-on? 

Yes, you can bring mascara in your carry-on. However, it’s important to note that mascara is considered a liquid, gel, or paste by most airlines. So, it must adhere to the liquid restrictions set by the airline or the security authority of the country you’re flying from. For the U.S., that means mascara must be in your 3-1-1 liquids bag and not just in a general makeup bag. It’s always a good idea to check with your airline or the security regulations of the country you’re departing from to ensure compliance.

Does toothpaste count as a liquid?

Yes, toothpaste is typically considered a liquid or gel by airline and security regulations. This means that if you’re bringing toothpaste in your carry-on bag, it must adhere to the liquid restrictions in place.

Final thoughts on packing toiletries in your carry-on 

Figuring out how to pack toiletries when traveling carry-on only can be a challenge…and it can also be highly personal. What works for one person may not work for you. 

You also might find that you enjoy the challenge of packing for longer and longer trips with a minimal number of toiletries. And certainly, with all the solid toiletries options available, you should be able to get any liquids you need into that 1-quart Ziploc bag.

Hello Darcy, loved reading your helpful articles. In one article you mentioned a Columbia rain jacket which I cannot find and I want to order it this week for an upcoming trip. Would you please tell me which Columbia rain jacket it is?

Hi, Valerie. I recommend the Columbia Arcadia II. I bought mine directly from the Columbia website. https://www.columbia.com/p/womens-arcadia-ii-rain-jacket-1534111.html .

Have a great trip!

I use contact lens cases for some of my lotions and moisturizers. I had an abundance of them leftover from the days when I wore contacts, so I began using them for travel. They are small, but can easily hold a week’s worth of moisturizer. Use different colored cases for different products, or label each one if you are afraid you won’t remember what is in each case.

That’s a great idea. Thanks so much for sharing!

Thank you for these great tips! Traveling to India and trying to wrap my brain around what to do for 20 hours and how to pack our carry ons just in case our luggage gets lost!

You’re so welcome! Have a wonderful trip.

Thank you Darcy. Traveling internationally for the first time. Of the sites I’ve read, yours was the most helpful regarding liquid carryons. Thanks again Joyce

Thanks so much for your kind words! I wrote this post because back when I went on my first international trip I also had trouble finding the information I needed to help me pack my liquids for carry-on only travel.

The TSA Liquid Limit You Need To Know For Airport Security

Last Updated on November 1, 2021

There are actually three TSA liquid limits for fluids, gels, pastes, and creams packed in your carry-on bag.

These liquid limits are enforced by the TSA when going through airport security.

The limits are not about the moment that you step on the plane. They are about the moment your bags go through the scanners at the security checkpoint.

Liquids that you buy after the airport security checkpoint can be brought onto the plane without restrictions.

Let’s look at the checkpoint guidelines and the three limits.

The Liquids Limit – TSA Rules & Guidelines On Bringing Fluids On Planes

Transportation Security Administration’s official website outlines its liquid rules, but they don’t do a very good job of explaining why the liquids limits are in place.

The contents of your carry-on bag will be scanned by the x-ray machine. Crucially, the TSA cannot identify from the scanner whether liquids really are what they say they are on the label.

The x-ray scanners can detect weapons, but they can’t detect flammable liquids.

Any passenger’s liquids could be explosives in disguise. This is why they are a security threat and why the TSA liquid limits exist. They want to make sure nobody is bringing a lot of liquids on the plane, just in case.

Here are the three liquid limits that the TSA imposes.

TSA Liquid Limit 1 – Only Travel Size Containers

You must carry liquids, gels, and aerosols in a travel-size container.

Travel-size means bottles that are 3.4 oz or less. If you are thinking 3.4 ounce is a strange number it’s exactly 100 ml and that is the standard maximum size of carry-on liquids around the world.

Check this post if you want to get a feel for what 3.4 oz looks like .

It is the size of container that is important, not the amount of liquid in the the containers. So half empty tubes of toothpaste don’t qualify.

Generally, larger containers with more than 3.4 fluid ounces cannot be packed in carry-on luggage.

If you exceed the liquid limit TSA will confiscate it and throw it in the trash. Although, the TSA prefers to say you “voluntarily surrender” the liquid since you could, in theory, choose not to fly.

TSA Liquid Limit 2 – A Quart Size Bag

All your travel-size bottles must be packed in a one quart sized bag .

There are 32 ounces in a quart, but you won’t be able to pack 32 ounces of liquids in your hand luggage. The shape of the bottles makes it awkward to pack a Ziploc baggie to the maximum.

The total liquids limit for the TSA is probably around 25 ounces. That would be 7 or 8 travel-size bottles packed in a quart-size plastic baggie.

The TSA says a 6 x 9 inches Ziploc bag is quart-sized, but there are other bag shapes that are suitable.

Go ahead and adjust the dimensions of the ziploc bag to find out if it's quart-sized and TSA approved.

You could also buy a reusable “quart size” bag from amazon. Most of them are actually larger than one quart but everyone seems to be getting away with it .

TSA Liquid Limit 3 – Only One Quart Bag Per Passenger

The 3-1-1 TSA rules only permit one plastic quart bag per passenger , that’s another limit, it’s not one bag per carry-on suitcase. So you can’t get around the TSA liquid limits by bringing more than one carry-on.

The 3-1-1 Rule

We can now see why it’s called The 3-1-1 Liquids Rule. There are 3 TSA liquids limits.

• Three point four ounces travel size bottles – the container size limit.
• In a one quart size plastic bag – the plastic bag size limit.
• And only one bag per passenger – the number of bags limit.

The TSA 3-1-1 rule is kinda confusing if you ask me. It should be called The 3.4 – 1 Rule but then that wouldn’t have been as catchy.

What does the TSA consider to be a liquid?

The TSA often says “If you can squeeze it, smear it, pump it, spread it, spray it, or spill it then it’s considered a liquid”.

That means that some items that you might not think are liquids are considered to be liquids by the TSA security officers.

A lot of travelers are caught out by spreads, creams, and gels. In the mind of the average person, something that doesn’t pour isn’t a liquid, but that’s not how the TSA defines it.

It can also matter whether the liquid is “flying solo” or is part of something.

For example, liquid food fillings that are part of solid food don’t count as liquids.

The classic example is peanut butter . Peanut butter in a jar is considered a liquid, whereas a PB&J sandwich is considered a solid.

And remember this from science class, frozen liquids become solids.

That’s true at the airport security checkpoint too.

Liquids that are restricted at room temperature become unrestricted if they are frozen solid. That means if a liquid is frozen the 3.4 oz limit does not apply. The challenge is getting the liquid to the airport while it is still frozen solid. The TSA will refuse to let it past if it is beginning to melt. Ice packs, coolers, and perhaps dry ice could help.

Some items that passengers get caught out by are gel packs, canned foods, snow globes, bug spray, and sunscreen.

Liquids That Are Never Allowed Through Security

There are some liquids that are never permitted on the plane even in travel-size bottles.

You cannot bring hazardous materials (Hazmat) flammable liquids on to the plane even in quantities smaller than 3.4 oz.

Examples are:

• Aerosols that are not toiletries
• Paint thinner
• Lighter fluid
• Lighter gas

Only travel-size aerosols that are toiletries are permitted in hand luggage. The definition of a toiletry is something that is sprayed on your skin. So aerosol deodorant is permitted, but aerosol air freshener is not.

Exemption To The TSA Liquids Limit

There are some liquids permitted in carry-on baggage in containers larger than 3.4 ounces

Liquid Foods For Babies & Infants

Feel free to bring water, juice, or soup for an infant.

You also don’t need to worry about breast milk or baby formula.

You simply put these items in a separate bin at for screening at the checkpoint.

When a child is able to walk through airport security unassisted by an adult they are no longer considered an infant and the exemption ceases to apply.

Medically Necessary Liquids

You can also pack reasonable quantities of medically necessary liquids in carry-on bags in containers larger than 3.4 oz.

Additional screening is required so place these liquids in a separate bin at the checkpoint.

You don’t need any documentation from your doctor.

Duty Free Alcohol

Duty free liquids that you have purchased after the checkpoint can be brought on to the plane.

If you have a connecting flight you should be able to bring the alcohol through the security checkpoint if it is in tamper evident bags.

Liquid Limits For Checked Baggage

Most toiletries that are limited in carry-ons are unlimited in checked bags.

The amount of shampoo, shower gel, and sun cream you pack in your checked bag is up to you.

Aerosols and flammable liquids still need special attention, as there are additional rules for these products .

Liquor that is above 24% ABV but less than 70% ABV is restricted to 5 liters maximum because it’s somewhat flammable. Liquor over 70% ABV is banned in both carry-on and checked luggage.

Take It To The Limit… One More Time

According to the Transportation Security Administration, liquids, gels, and aerosols packed in hand luggage can only be 3.4 ounces or less when going through the airport security checkpoint.

You must pack all your liquids in one quart-size bag.

You can only have one bag per passenger.

Calling All Travelers: These Are the Official TSA Liquid Rules

You don't want security to throw away your new, full-size bottle of shampoo do you?

Every item on this page was chosen by a Town & Country editor. We may earn commission on some of the items you choose to buy.

We've all fallen victim to TSA while traveling; here's a refresher so you don't make the same mistakes again.

TSA Liquid Rules:

According to the TSA website , these rules apply for liquids, aerosols, gels, creams, and pastes.

All liquids must be in a 3.4oz or smaller container. Your serums, creams, cleansers, and masks are too expensive to lose, so check their sizes and if they're too big, leave them at home or transfer them to a smaller container.

They have to be able to fit in a quart-size bag. Before you throw 10 containers of liquids into your carry-on, make sure that everything can fit in a quart-size bag. Think about what you really need for your trip, a la Marie Kondo , and remember you can always buy things once you arrive at your destination.

Powders must be in 12oz containers or smaller. TSA placed new restrictions on powders in 2018. Ensure that your makeup, protein powder, and baby powder are in containers within that range, or put them into a checked bag.

Anything else has to go into a checked bag. If you can't part with your full-size products, they have to go into a checked bag to avoid getting tossed into the TSA product graveyard. If you're looking to save money, share one checked bag with your whole group.

Only empty water bottles will pass the TSA checkpoint. If you bring a refillable water bottle, make sure it's empty before you approach security. You can fill it up after you go through the checkpoint or buy water in the terminal.

There are exemptions. If you use a medication that comes in liquid, aerosol, gel, cream, or paste form and the container is larger than 3.4oz, it's exempt from the above rules. Similarly, if you're carrying baby formula, breast milk, or other liquid foods for your child, these are also exempt.

TSA Liquids Rule Explained: What Size Liquid Can You Bring on a Plane?

What you can and can’t bring on a plane, including the amount allowed, can be very confusing for even the most experienced of flyers, especially when it comes to liquids.

According to TSA regulations, you are allowed to bring liquids in containers that don’t exceed 3.4oz/100ml in your carry on.

There are also limits when liquids are packed in your checked bags, which many people are not aware of, though the limits are much greater.

What Size Liquid Can You Take on a Plane?

Carry on bags.

The TSA has a rule in place called the 3-1-1 Rule .

The 3-1-1 Rule states that “each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or 100 milliliters .”

These containers must also fit in a 1-quart sized, resealable bag.

You are required to take this bag out of your carry on and place it in a screening bin as you go through airport security.

Note that it is the size of the container itself and not how much liquid is in the container that matters.

So, if you have a bottle that contains just 1ml of liquid inside a 4oz container, it still won’t be allowed through.

Checked Bags

Not many passengers are aware that there are restrictions on the quantity of liquids you can pack in their checked bags.

According to the TSA:

• A container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
• The total aggregate quantity of your toiletry products must also not exceed 2 kg (70 ounces) or 2 L (68 fluid ounces).

No Differences For International Flights

Even though it may not be called the 3-1-1 rule worldwide, the rules remain the same if you’re flying internationally.

So regardless if you’re flying from or within Mexico, Canada, the UK, Europe or any other country, you are only allowed to pack liquids (as well as gels and aerosols) in containers that are no larger than 3.4oz/100ml in your carry on.

Airlines Follow TSA Regulations

All airlines follow TSA regulations .

So this means that regardless if you’re flying with Delta, Southwest, American Airlines, JetBlue, or any other regional or major air carrier worldwide, you are only allowed to bring liquids in containers that do not exceed 3.4oz/100ml in your carry on.

How to Pack Liquids for Flying

There are a few guidelines you should follow to make your next flight go as smoothly as possible.

• Make sure that no container you want to bring is no larger than 3.4oz/100ml.
• Buy travel-friendly products of your favorite products.
• If the company doesn’t sell travel-friendly sizes, buy your own 3.4oz/100ml containers and transfer the liquids into them.
• Consider packing non-liquid alternatives instead (you can bring a bar of soap on a plane on a plane , for example, with no restrictions. The same applies to sunscreen sticks ).
• Share toiletry space with your travel partner, as the 3-1-1 Rule applies to each passenger.
• Store your items in a clear bag that is no larger than 1 quart.
• Use your checked luggage for liquids in larger containers.

You Will Be Able to Bring 7-8 Bottles in Your Carry On

In total, you can take 32 ounces (or 1 quart) of liquids on a plane.

But as the containers themselves will take up space in the single quart-sized bag, you won’t be able to take a full 32 ounces of liquids in your carry on.

You will be able to bring about 25 ounces in total, in 7 or 8 travel-sized 3.4oz/100ml containers onto a plane in your carry on.

How Many Ounces in Total Can You Take On a Plane?

Carry on bags.

As just mentioned, you can bring 32 ounces (or 1 quart of liquids on a plane), though it will more likely be 25 ounces in 7-8 bottles.

If liquids are packed in your checked bags, each container must not exceed 18 ounces or 17 fluid ounces).

The total aggregate quantity of your toiletry products must also not exceed 70 ounces or 68 fluid ounces.

A Loophole to Bring More Than 3.4 Oz/100ml On a Plane

There is a loophole that lets you bring more than 3.4oz/100ml of liquids on a plane, though it only works with very few items and under certain circumstances.

If you are traveling with a young child or baby, you can say that the item is for them.

Of course, this will only work for bringing a water bottle on a plane and not items like alcohol, coffee or tea . 

Exceptions to the 3-1-1 Rule

There are several exceptions to the 3-1-1 Rule.

The following items, if packed in your carry on bags, are allowed to exceed 3.4 oz/100ml:

• Breast milk and formula
• Liquid medication
• Hand sanitizer
• Jumbo disinfecting wipes
• STEB items (secure, tamper-evident bags purchased at the airport)
• Cough syrup
• Gel-filled bras
• Saline solution
• Ice packs (must be frozen solid)

Liquids That Are Forbidden

There are several liquids that, even if under 3.4 oz/100ml, you are not allowed to bring on a plane in either your carry on or checked bags.

These items include:

• Most flammable liquids ( you can bring nail polish on a plane , though)
• Most toxic liquids
• Aerosols that do not qualify as toiletries
• Alcoholic Beverages over 70% ABV (140 proof)
• Insecticide
• Spray Paint
• Spray Starch
• Cooking Spray

Surprising Items That Qualify As Liquids

There are also items that you wouldn’t expect to count as liquids, but actually do.

• Peanut butter
• Hair mousse
• Snow globes

What the 3-1-1 Rule Stands For

The 3-1-1 Rule stands for 3 ounces, 1 passenger, 1 quart-sized bag.

While the limit is actually 3.4 ounces instead of 3 ounces, we guess that 3.4-1-1 Rule didn’t have the same ring to it.

Why the 3-1-1 Rule Exists

The 3-1-1 Rule exists because terrorists have previously tried to sneak liquid explosives on a plane on more than one occasion.

While the rule is frustrating, it exists for the safety of passengers.

Carry-on bags

Know what you can carry on

There are some items that can only travel in your carry-on bag (and some items that must be checked). Make sure you know where to pack these restricted items – and if you can carry them on.

Restricted items

• TSA restricted items Opens another site in a new window that may not meet accessibility guidelines

1 personal item and 1 carry-on

Personal items.

Your personal item like a purse or small handbag must fit under the seat in front of you. Dimensions should not exceed 18 x 14 x 8 inches (45 x 35 x 20 cm).

These don’t count as your personal item or carry-on:

• Diaper bags (1 per child)
• Breast pump
• Small, soft-sided cooler of breast milk
• Child safety seats, strollers and medical or mobility devices

Carry-on items

You can bring only one carry-on item along with your personal item. Your carry-on must fit in in the overhead bin or under the seat in front of you. If it doesn’t fit, it will need to be checked. Be sure all your carry-on items are labeled in case they are checked.

Some airports and planes may have additional carry-on restrictions.

Carry-on bag

The total size of your carry-on, including the handles and wheels, cannot exceed 22 x 14 x 9 inches (56 x 36 x 23 cm) and must fit in the sizer at the airport.

Soft-sided garment bag

Your soft-sided garment bag cannot exceed 51 inches / 130 cm (length + width + height).

Musical instruments

Your musical instrument must fit in the overhead bin or under the seat in front of you.

Traveling with musical instruments

Regional flights on American Eagle ® planes have limited overhead bin space. If your carry-on is larger than the personal item dimensions, you must valet your bag before boarding.* We’ll tag and check your bag at the gate for you free of charge. When you arrive, you’ll receive your bag on the jetbridge after exiting the plane.

Remove any batteries, electronic cigarettes and other restricted items from checked bags.

*Embraer ERJ-175 planes allow carry-on bags and don’t offer valet service.

Carry-on pets

For carry-on pets, review our policy for guidelines, limitations, and restrictions.

Traveling with carry-on pets

TSA allows certain duty-free liquids through security in your carry-on bag if they’re packaged in a security tamper-evident bag. If you’re traveling with liquids or are unsure about any item, please contact the TSA.

Maximum Liquid You Can Take on a Plane in Carry On?

John Parker

It can be quite confusing to know what the carry on bag liquid limit is and also what is considered to be a liquid under the Transportation Security Administration (TSA) 311 rule.

By following the TSA liquids rules you will pass through airport security much quicker and with fewer problems. You will also ensure that you don’t have any expensive toiletries etc taken away from you.

Hopefully, this article will thoroughly explain the carry-on liquid limits and clarify them so you don’t break the TSA regulations.

The Quick Answer: The TSA rules for flying with liquids specify that liquids on planes must be in containers that are no larger than 3.4oz/100ml each in order to be taken through airport security. All the liquids you are carrying must fit into one quart-sized resealable plastic bag.

Carry on liquid size policy?

The TSA uses what it calls the 311 rule.

The description of the 311 rule is a little tenuous as the 3 isn’t entirely accurate. What it means is quite easy to understand, though:

The carry on liquid size of 3.4 ounces (100 ml) refers to the maximum size of the container, not necessarily the amount of liquid held in it. So, for example, you cannot take a container of deodorant that held 6 ounces when full but is now less than half full.

If traveling to or within Europe, the allowable size for your bag of liquids is 1 liter. This is slightly larger than one quart, so if you have a TSA-approved quart-sized bag, you will be fine.

You can buy an approved liquids bag on Amazon relatively cheaply and some come with empty travel-sized containers to put liquids in – TSA 3-1-1 Approved Clear Airline Carry On Bag

Larger liquid containers must go in your checked bag. See How much liquid can you take on a plane in checked baggage?

What to do with your liquids at the security point

When you get to the TSA checkpoint, hopefully after not too long a wait, you must remove the quart-sized resealable bag containing your liquids from your carry on and place it separately in a tray to go through the x-ray machines.

Please do not leave them in your carry on bag; otherwise, you will be delayed and have to put them through again.

This is the official Transportation Security Administration video explaining the 311 liquids rule and the maximum liquid permitted in carry on bags in an airplane:

What is considered a liquid for airport security?

I think the 311 liquid rule is pretty clear.

Now, what is and is not considered a liquid is rather less straightforward, so I will try to give as complete a description as possible and then answer some of the most often-asked questions.

The easy answer is that almost anything that isn’t solid is considered a liquid, such as liquids, gels, and aerosols.

These include:

• Liquids – pretty obvious, really but they include shampoos , hair conditioners, liquid soaps, bottled water and cans of soda
• Aerosols – such as deodorant , body sprays etc
• Gels – shaving gel, gel lip balm
• Creams – face and hand creams, skincare, shaving cream, suncream , moisturizer and toothpaste
• Powders (even these can be considered a liquid)

You can buy many of these in travel-size containers.

Read my post – 9 things considered a liquid when flying that aren’t

What makeup counts as liquid on a plane?

Some types of makeup are pretty obviously liquids, but just to be clear, the following is considered a liquid, so it is subject to the restrictions and rules detailed above.

• Nail polish
• Nail polish remover
• Tube mascara
• Liquid, cream or gel eye shadow
• Gel lip balms
• Liquid foundation (powdered is fine proved it is less than 12oz)

Also read: Can you bring make-up on a plane ?

Are there any exemptions to the liquid rule?

There are some exemptions to the 3-1-1 liquids rule. These exceptions mean they can be in containers larger than 3.4 ounces, and they do not have to go in the quart-sized plastic bag, although they do need to be placed in a separate bin for additional screening.

Read my post for full details: What liquids do not go in a liquids bag?

Liquid medication

It is possible to carry medically necessary liquids larger than 3.4 ounces to treat certain medical conditions. These include saline solution used to clean contact lenses , lotions, liquid antibiotics, etc.

It doesn’t matter if the liquid is in a bottle, an aerosol, a cream or in gel form.

The full updated details are best read on the TSA website – Disabilities and Medical Conditions

Baby and infant products

There are exceptions if you are traveling with a baby or infant, but you must have the baby with you, which may sound rather obvious but means you cannot carry it for someone else. Breast milk can be carried without a baby, though.

You can take “food” items for the baby in reasonable quantities through airport security that exceed the 3.4 ounces/100ml rule, such as:

• made-up baby formula
• expressed breast milk
• sterilized water to make up baby formula (must be in a baby bottle)

You should tell the TSA officer that you have these before you put them through the x-ray machine for additional screening.

You can read my more detailed article about flying with a baby or toddler

You are allowed to carry duty-free liquids provided they are in unopened, secure, tamper-evident bags (as supplied by the duty-free store) if more than 3.4 oz or 100 ml in your carry-on bag and also if the following is true:

• The duty-free liquids were purchased internationally, and you are traveling back to the USA with a connecting flight.
• The liquids are packed in a transparent, secure, tamper-evident bag by the duty-free store, and they have not been tampered with or opened when shown at airport security.
• You have the original receipt for the liquids.
• The purchase was made within the previous 48 hours.
• The items in their bags should be removed from your carry-on and screened separately.

Liquids you cannot take in carry on

Several liquids cannot be carried in hand luggage. Most of these are flammable or hazardous.

These include :

• cooking fuel
• lighter fuel
• pepper spray and other self-defense sprays
• liquid bleach

Airline liquid rules

Don’t forget that these limits do not refer to the maximum amount of liquid allowed on a plane but the maximum allowed to be taken through airport security.

Airline liquid rules allow any liquids that are permitted through airport security. Plus, once you are through the TSA checkpoint, you can purchase any reasonable amount of liquids from any stores in the departure lounge and take these on the aircraft with you.

You can also fill water bottles from a water fountain or buy bottled water.

Useful tips for carrying liquids in carry on

These days, particularly with budget airlines, it costs extra to take checked bags so many passengers opt to travel with only carry on , particularly if it is a relatively short trip.

This can present a problem with many personal hygiene products, such as shampoo, conditioners, face creams etc as they generally come in bottles that are too large to go through airport security.

So you either have to:

• find your favorite brands in bottles small enough to go through security (which often isn’t possible)
• try and buy some larger bottles when you arrive at your destination. But that may prove not so easy, particularly if traveling overseas. Even if you can, it also means you are likely to throw away much of what you have bought before you return as you can’t take it with you due to the liquids rules, which is a waste.

The solution is to buy some refillable bottles that meet the liquid rules and fill them up from your larger containers before you leave home.

These are some that I have used that also come with a TSA approved quart-sized bag and a folding toothbrush .

The TSA liquid rules state that liquids must be in containers no larger than 3.4oz/100ml each to be taken through airport security. All the liquids must fit into one quart-sized resealable plastic bag. Only one plastic bag containing liquids is allowed per passenger in carry on.

Liquid limits in carry on could be scrapped once 3D scanners fully operate at airports.

How many Ziploc bags can I take on a plane?

Only one ziplock liquid bag containing liquid items may be taken through airport security per passenger.

Can you bring multiple 3 oz bottles on a plane?

Yes, you can take as many 3.4-ounce bottles containing a liquid on a plane as you can fit in a quart-sized liquids bag.

Are makeup wipes considered a liquid?

Makeup wipes, baby wipes, and sanitizer wipes are all allowed on a plane as they are not treated as a liquid.

Is toothpaste considered a liquid?

Toothpaste is considered a gel or cream and so for airport security is treated in the same way as a liquid. This means that you can take a small travel tube that is less than 3.4 ounces, and it must go in a quart-sized liquid bag.

Is deodorant a liquid for air travel?

Deodorants are treated as liquids on a plane unless they are solid “stick” deodorants, so any others must be 3.4 ounces (100 milliliters) or less.

I have been traveling around the world by air since the early 70s and living overseas too. I worked for British Airways for a number of years and I am also a private pilot. About Me

Rules for Liquids in Checked Baggage: The Complete Guide

DIY Ways to Secure Your Packed Liquids

Go with the pros, add padding, anticipate inspections, tips for packing liquids in checked baggage.

You can carry liquids in checked baggage, but you will have to do some research and take precautions. First, you must find out which liquids are not allowed on airplanes regardless of where you pack them. The Transportation Security Administration (TSA) has a list of these prohibited liquids on its website . You should also look at the Federal Aviation Administration's list of hazardous materials. Never try to bring prohibited materials with you when you fly.

After you've done your research, you must determine whether you can bring the liquid items of your choosing to your destination. If you plan to carry several bottles of wine, for instance, you may not be able to bring them into certain U.S. states due to liquor import regulations. Travelers flying to or from Canada will want to read the Canadian air travel regulations, and visitors to the UK should read the United Kingdom's list of items you may carry in hand (carry-on) and hold (checked) baggage.

Your next step is to decide whether you want to pack colored liquids, such as red wine or nail polish, which could damage your clothing. Carrying any colored liquid can be risky. Decision-making factors include whether these items are available at your destination and whether your itinerary is flexible enough to allow you to purchase them locally, rather than bring those liquids with you.

Finally, you will need to carefully pack your liquid items so they will not break or leak. There are several ways to accomplish this. Read on for our complete guide on what to know before packing liquids for your next trip.

To prevent leaks, wrap the top of your bottle or container with duct tape so the cap stays on. (You may also want to pack a small pair of sharp scissors in your checked bag so you will be able to remove the tape later.) Put the container into a zipper-top plastic bag and seal the bag closed. Next, place that bag into a larger zipper-top bag and seal it closed, pressing out all the air as you do so. Wrap the whole thing in bubble wrap if the container is breakable. Finally, wrap that bundle in a towel or in clothing. (Many travelers suggest using dirty laundry for this.) Place the wrapped bottle or container in the middle of your largest suitcase, surrounded by clothing and other soft items.

A variation on this method involves using a hard-sided plastic or cardboard container to protect your liquid item. Use a small cardboard box or a sealed plastic container. Double-bag the liquid item as described above. Then, place it in the container and pad it with crushed newspapers, plastic air pillows or crumpled plastic grocery bags. Tape the box shut and pack it in the center of your suitcase.

You can buy styrofoam or bubble wrap "shippers," which are sealable padded bags. Brand names include the inflatable VinniBag or the Wine Mummy. Boxes made especially for transporting glass and liquid items are another option. Your local wine shop or pack-and-wrap store may carry shippers. Be aware that the bubble wrap bags will keep escaping liquid from staining your clothes, but may not prevent glass bottles from breaking. The box shipper will take up more room in your luggage. While it may not prevent liquid from escaping, the box shipper minimizes the risk of breakage.

Protect your liquid items by placing them in the middle of your suitcase, completely surrounded by clothing and other items. Be aware that your suitcase could be dropped or crushed, perhaps more than once, on its way to your destination. It may even be dragged on the ground behind a luggage cart. If you can choose from several suitcases, pick the one with the stiffest sides and pack it as tightly as you can to better cushion your liquid items.

If you pack liquid items in your checked bag, assume that your bag will be inspected by a baggage security screener. The screening officer will see your liquid item on the baggage scanner and will probably need to take a closer look at it. Do not pack valuables, even liquid ones, or prescription drugs in your checked baggage.

• Careful packing and padding will increase your chances of success, so make sure to transfer all liquids to leak-proof containers.
• Pare down your packing. Not everything can fit in your suitcase! Decide what toiletries you may find up for grabs in your hotel room, and edit, edit, edit.
• Two-in-one items are always a good idea.
• If you have a large-sized soap or shampoo that you really want to take on your trip, invest in travel-sized toiletry bottles . This way, you can pour some into the correctly sized bottle and still be allowed to take it with you on your trip.

One of the most common questions in the TFG community is how strict the clear bag policy is for European travel. If you’re wondering the same thing, this article will cover everything you need to know, as well as offer some great tips for easily achieving the 3-1-1 rule. Take a look!

Europe Travel – What Size Clear Bags for Liquids In Carry On

Table of contents.

While the TSA rules for liquids in carry on bags is pretty clear when leaving the United States, when it comes to traveling around Europe and hopping from country to country, some readers feel unsure on this topic. Exactly how strict is the 3-1-1 liquids rule in this popular continent?

When we asked TFGs this very question, the overall consensus was that European airports are usually quite strict when it comes to checking liquids, both in terms of the bag being clear and the bag’s size.

While it’s true that some airports in Europe are a bit more lax and may not require the bag to be transparent, it’s definitely better to be prepared with one, just in case. That way, you’re not holding up the security line and won’t run the risk of having to display your liquid products directly in the TSA bins — yuck!

Heading to Athens with my Osprey Transporter Wheeled 38L Carry-On and Osprey Transporter 44L Carry-On Bag where I had to present my 1 quart-sized bag!

The 3-1-1 liquids rule means 3.4 ounces (or 100ml), 1 quart-sized bag, and 1 bag per traveler. For a more in-depth rundown on this rule, take a look at our 3-1-1 article here !

These liquid limitations mean that a bit of toiletry downsizing is probably required. So, if you’re packing for Europe and want to make sure that going through security with your liquids will be a breeze, here are some top tips!

How To Achieve the 3-1-1 Rule for Europe

EzPacking Clear TSA Approved 3-1-1 Travel Toiletry Bag

Have a TSA-Compliant Clear Toiletry Bag Ready

A clear bag is a must to ensure a smooth and hassle-free airport experience. You’ll always need to take out your liquids when going through security, and readers agree that most European airports will require a clear bag in a TSA-approved size.

Cableinthebay TSA Approved Clear Travel Toiletry Bag

While you could use the bags provided, Instead of doing this, it’s wise to bring your own clear bag that’ll keep your toiletries organized and clean! It’s recommended you have your 1-quart size bag ready and outside of your suitcase, so you can simply drop it into a tray at security and have a smooth inspection.

However, be prepared, as some European countries require you to use their bags. Readers say the trick is to transfer things over as quickly as possible, and after you go through the scans, put them all back into your own bag.

Paylak Stackable Travel Container

Go Small and Use Stackable Pots

Items like foundations, creams, gels, and other thick products still count as liquids and will need to go in your 3-1-1 bag. But if you don’t need an entire 3.4 oz travel bottle for some of those products, one amazing solution is to use small, stackable pots !

One reader shares that most travel-sized products and containers are too much for her, even on multi-week trips, so she opts for decanting into these smaller tubes.

Because you can vary the sizes, say around 1 or 2 oz, handy little pots will save SO much space in your bag. This is definitely the answer for those products that you’ll only need a little bit of throughout your trip!

HiBAR Shampoo and Conditioner Bar Set

Replace Liquids With Solid Alternatives

One of the most efficient ways to downsize your liquid toiletries is to simply switch them over to a non-liquid version. Solid toiletries won’t count towards the 3-1-1 rule, and you won’t have to put them into your clear bag for security.

You’d be surprised how many products come in solid form, from lotion to face wash to sunscreen! You can even switch things like toothpaste, laundry detergent , and bug repellent over to a solid form, and they’re just as effective. A lot of readers love HiBar’s solid shampoo and conditioner sets , which come in a wide range of options depending on your hair needs.

The Original Erase All Makeup

Kitsch Toiletry Pouch Set

Flat Toiletry Pouches

Flat travel containers are incredible because they can fit a lot of products but also won’t take up any extra space if you don’t need to fill them up all the way. Another great bonus is that as you use up what’s inside, it’ll get smaller and smaller, leaving you with extra space in your bag!

Readers love that they’re super slim, flexible, and easy to pack while being sturdy and leakproof. One of their top picks is from Kitsch, which comes in a three-piece set or in a larger 11-piece set that covers all the bases with pump bottles, pots, and a spray bottle!

Neutrogena Beach Defense Water-Resistant Sunscreen Stick

Buy Products at Your Destination

Many readers share that a great way to save space in your luggage is to simply buy products at your destination, especially bigger ones like shampoo, conditioner, body wash, and sunscreen . Though, do some research beforehand to make sure you’ll have access to the right shops.

One reader shares that there are beauty shops and pharmacies all around the world and that you might just discover some new favorite products in them!

Embryolisse Lait-Crème Concentré, Face Cream & Makeup Primer

She adds that it’s a great way to learn about the area. (If you’re heading to Paris , readers RAVE about French pharmacies — they have amazing products at really affordable prices!)

With this method, you’ll be able to reduce a good amount of space and weight in your bag, saving room for an extra pair of shoes or some souvenirs on the way home!

BAGSMART Toiletries Travel Bag

Load Everything Back Into a “Carry-All” Toiletry Bag

The best toiletry bags will have plenty of pockets and compartments to store all of your products and then fold up neatly and compactly.

3-1-1 Guide for Most Popular Destinations

Here is a short guide on some of the most popular destinations and their 3-1-1 policies:

The 3-1-1 rules are generally very strictly enforced in most airports around France.

Many airports, including CDG in Paris, provide their own clear baggies in case your toiletries aren’t in a (very) similar-looking one. Some readers have experienced the security at CDG requiring everyone to put their liquids into the provided bags, while other readers were able to get through with their own TSA-compliant bags, so the closer you can get to their bags, the better.

New scanners are currently being tested at some of the major airports in France that will eventually allow you to leave your liquids in your suitcase, but for now, you’ll need to abide by the 3-1-1 rules and separate your liquids for a smooth experience.

If you need more help packing for France, review our Paris Packing Guide !

The 3-1-1 clear bag rule for liquids is the same in Italy as it is in France, so as long as you follow those guidelines you’ll be good to go!

There are also a few airports in Rome and Milan that have high-tech scanners that don’t require you to take your liquids out of your suitcase as it goes through TSA (but the 3-1-1 size limits still apply). Even with these new scanners popping up, it’s still recommended to have your clear liquid bag ready to be taken out if need be, as not all terminals or security lines are guaranteed to have those new scanners.

If you need more help packing for Italy, review our Ultimate Italy Guide and our Rome Guide !

Multiple airports in Madrid and Barcelona are expected to implement new 3D scanning technology in 2024 that will allow travelers to leave their liquids in their luggage and even carry on full-sized products. However, as of now, the standard 3-1-1 rules apply.

When traveling through Spanish airports, have your one transparent, quart-sized bag at the ready to pull out for individual scanning, and be sure each product is travel-sized.

If you need more help packing for this region, review our Ultimate Spain Guide !

United Kingdom

London Heathrow abides by the traditional 3-1-1 rule, and readers say it’s one of the strictest airports in Europe. LHR (as well as Gatwick) states that your liquids must be carried in a transparent and resealable bag that’s no larger than 20 cm x 2 0cm (8 in x 8 in) and can be closed with everything inside. Many readers report being required to transfer their items to the clear bags provided by these airports while others reported having no issues using their own clear bags.

London City Airport has fully adopted new scanning technology that actually removes the 100 ml/3.4 oz liquid limit, allowing travelers to carry liquids of any size, as long as they stay under 2 liters altogether.

And at other UK airports, while new scanning technology is in the works, for now, you’ll need to make sure your liquids are in a single, clear, quart-sized bag.

If you need more help packing for this country, review our London Packing Guide !

In Dublin and most other airports in Ireland, the usual TSA rules for liquids are enforced, and you’ll need to present your liquids bag when going through the screening. As long as your toiletry bag is transparent, resealable, and no bigger than 1 liter, you’re allowed to bring whatever bag you’d like.

Shannon Airport and Donegal Airport have both introduced those high-tech TSA scanners that allow liquids bigger than 100 ml/3.4 oz. This means you can bring full-sized toiletries (limited to 2 liters total) in your hand luggage! (But keep in mind that this is only when flying out of these airports.)

This Hack Lets You Bring Larger Liquids Through TSA — What to Know

Can you actually bring frozen liquids through airport security? We found out.

3-1-1 Liquids Rule

Carrying frozen liquids through tsa, bottom line.

AzmanJaka/Getty Images

You’re heading on a trip to celebrate warm weather when you encounter a problem. You aren’t checking a bag, so you have to fit all your toiletries (shampoo, conditioner, face wash, body wash, perfume, etc.) in one quart-sized bag. You also want to fill your Stanley tumbler up with your favorite beverage to drink during your flight, but you have to go through airport security. Millions of travelers face the same issue thanks to the 3-1-1 liquids rule from the Transportation Security Administration (TSA). 

Recently, a clever “travel hack” went viral on TikTok . It suggests that if you wish to carry larger liquids onto your plane, you can freeze them before reaching the airport and take them through security. We spoke with the TSA to confirm the validity of this method and understand any potential restrictions. 

Here’s everything you need to know about carrying frozen liquids through airport security. 

According to the TSA, you must follow the 3-1-1 rule for liquids in your carry-on baggage. This rule states you can bring one “quart-sized bag of liquids, aerosols, gels, creams, and pastes in your carry-on bag and through the checkpoint.” Each item inside the bag must be smaller than 3.4 ounces or 100 milliliters. Any liquids that are larger than this or do not fit inside your single quart-sized bag allotment must be packed in your checked bag. 

Keep in mind that things you don’t typically think of as liquid may still fall under this rule. Since it’s spreadable, peanut butter is considered a liquid for TSA purposes and must be smaller than 3.4 ounces to go through the checkpoint. I ran into this issue a few years back when trying to bring jam home from Italy. In my mind, it was solid, and I thought I’d have no problem flying from Italy to the U.S. However, when I tried to board my connecting flight to my final destination, I had to check my bag or throw out the jam.

While the 3-1-1 rule is strict, there are two important exceptions: medications and infant and child nourishment. According to the TSA website, “TSA allows larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your flight, but you must declare them to TSA officers at the checkpoint for inspection.” Similarly, formula, breast milk, toddler drinks, and baby/toddler food are considered medically necessary liquids, so you can bring larger quantities of these through the checkpoint. Still, you will need to inform the TSA officer.

You are also able to carry larger quantities of duty-free liquids in transparent, secure, tamper-evident bags if they were purchased internationally and you are traveling to the United States with a connecting flight. Note that you need to have the original receipt for the liquids and must have made the purchase within 48 hours.

So, is there truth to the frozen liquids hack? Yes, but with some caveats. Frozen liquids are allowed through security as long as they are completely frozen. If they are partially melted, slushy, or have any liquid at the bottom of the container, they must meet the standard liquids requirements. Ultimately, the TSA officer will decide whether an item is allowed through the checkpoint.

“Fully frozen liquids are acceptable as solids at TSA checkpoints in greater quantities,” a TSA spokesperson told Travel + Leisure . “Liquids, gels, and aerosols – which include those things you can spray, spread, spill, pump, or pour – are subject to TSA’s 3-1-1 rule at airport checkpoints.” 

Many of the liquids you want to get through TSA, like shampoo and toothpaste, cannot be frozen. In those cases, this hack won’t get you very far. Although you can freeze water, it will likely be more effort than it’s worth, especially considering most airports have water fountains you can use to fill up your water bottle for free on the other side of security. Plus, if you don’t have TSA PreCheck or Clear and end up waiting a long time to get through security, your frozen drink might start melting and will have to be thrown out anyway. 

Yes, you can bring frozen liquids over 3.4 ounces through TSA, but they must be frozen completely solid. Is this a travel hack that I’ll regularly use? Probably not. I’d rather fill up my water in the airport lounge than carry around ice and wait for it to melt.

Travelling with powders, liquids, aerosols and gels

Domestic flights.

Flights within Australia are not subject to restrictions on how much powder, liquid, aerosols and gels you can carry onboard.

However, if you are travelling domestically, but departing from an international terminal (for example, Terminal 1 in Sydney or Terminal 2 in Melbourne—your boarding ticket will confirm if you are departing from an international terminal), you are subject to powder, liquid, aerosol and gel restrictions.

In particular, all aerosol containers must have a fitted cap, or locking device.

International flights

Australia restricts the quantity of liquids, aerosols, gels and certain powders you can carry onboard international flights only. These restrictions do not apply to your checked-in baggage. This applies if you are:

• leaving Australia
• transiting through Australia from another country
• travelling on the domestic leg of a flight departing from an Australian international terminal, e.g. passengers departing Sydney international airport on a flight to Melbourne.

Restrictions on liquids, aerosols and gels also apply if you are arriving on international flights.

These restrictions are strictly applied. Security screening officers have the final say if there is any doubt about what items can be carried onboard.

You are also advised to check the  dangerous goods  restrictions.

What are powders, liquids, aerosols and gels?

Powders, liquids, aerosols and gels are:

• Liquid—a substance that is liquid when at room temperature.
• Aerosol—a substance kept in a container under pressure.
• Gel—a jelly-like substance.
• Powder—fine dry particles produced by the grinding, crushing, or disintegration of a solid substance (for example, flour, sugar, ground coffee, spices, powdered milk, baby formula or cosmetics). Powders may also be presented in clumpy, grain, or compressed material forms. Note: Inorganic powder is a powder not consisting of, or derived from, living matter.

Quantity restrictions

• There is no limit on organic powders, such as food and powdered baby formula.
• There are quantity restrictions on the amount of inorganic powder that can be carried, such as salt, talcum powder and sand.
• Inorganic powders must be in containers of 350 millilitres (volume), 350 grams (weight) or less.
• The total volume of inorganic powders must not exceed 350 millilitres, 350 grams per person. 
• Passengers cannot tip powders out to fall under the 350ml threshold as the restriction is calculated on total container volume.

There are no restrictions on the number of containers of inorganic powders per person, provided the total volume of all the containers of inorganic powder is 350 millilitres or less.

At the screening point all powders in your carry-on baggage must be separately presented for screening. Unlike liquids, they do not need to be put in a re-sealable plastic bag.

Liquids, aerosols and gels

• Liquid, aerosol or gel items must be in containers of 100 millilitres (volume), 100 grams (weight) or less.
• Containers must fit into one transparent and re-sealable plastic bag like a snap-lock sandwich bag.
• The four sides of the bag's sealed area must add up to no more than 80 centimetres (e.g. 20x20 cm or 15x25 cm).
• Only one bag is allowed per passenger, with exceptions for carers who may carry the bag/s for people in their care, including children.

Containers larger than 100 millilitres or 100 grams, even if only partially-filled, containing liquids, aerosols or gels will not be allowed through the security screening point. For example, a 200 gram toothpaste tube that is half-full will not be permitted.

At the screening point all liquids, aerosols and gels in your carry-on baggage must be separately presented for screening.

Some items may not be obvious, such as snow domes or toys and souvenirs with liquid, sand or granular material inside. If you are unsure if an item will pass screening, pack it in your checked baggage.

Examples of powders

Examples of liquids, aerosols and gels.

• Fact sheet - travelling with powders, liquids, aerosols and gels

Powdered baby formula, prescription and non-prescription medicines (including special dietary products), and medical items required during a flight are exempt. For medicines and medical items, you will need to present these items along with proof (e.g. doctor's letter) at the screening point. Cremated human remains are also exempt.

All organic powders are exempt. This includes most powdered foods, coffee, protein powder and baby formula.

The U.K. Ended Its Travel-Size Liquid Rule for Carry-Ons—Will the U.S. Do the Same?

By Jessica Puckett

Passing through airport security in the U.K. is about to get easier and more streamlined, as U.K. officials announced that the rule mandating liquids in carry-on bags be 100ml (3.4 ounces) or less will no longer be enforced, starting in June 2024. 

When the rule ends, passengers will be able to carry-on liquids measuring up to two liters in volume, the BBC reports . Additionally, passengers will no longer need to remove electronics from bags, such as laptops. Previously, major airports in the U.K., such as London Heathrow, were known for their stringent enforcements of the liquid rules.

In the U.S., similar policies are still in effect at airports around the country, with the TSA enforcing its so-called “ 3-1-1 ” liquid rule for carry-on bags: all liquids must be 3.4 ounces or less and fit in a single, one-quart clear bag. (Though there are  some exceptions to those rules.)

The more relaxed screening policies in the U.K. are possible thanks to new X-ray scanners that use computed tomography (CT) technology to produce more detailed, 3D images of luggage contents. (The technology is similar to a CT scan you might get at a hospital.) Most airports in the U.K. will need to upgrade their X-ray machines to the newer high-tech versions by June 2024. 

The same enhanced CT technology has been in use at U.S. airports for several years now, with the TSA rapidly expanding the scanners to dozens of airports nationwide. As of May 2022, the agency said it had deployed at least 402 CT units to 163 airports around the country. Over the summer, officials installed more of the scanners at additional airport checkpoints in anticipation of an uptick in air travelers, including at Billings Logan International Airport in Montana , Albany International Airport in New York, Buffalo Niagara International Airport in New York, Cincinnati/Northern Kentucky International Airport and Raleigh-Durham International Airport in North Carolina, the TSA  said in a release . 

With that in mind, will the TSA follow the U.K.’s lead and ditch its rules for carry-on liquids? Currently at U.S. security checkpoints with CT scanners, passengers already have somewhat more relaxed screening rules, as they aren’t required to remove their travel-size liquids, electronics, or food from their carry-on bags, according to the TSA. That was a precursor step to the new U.K. policy at  London City airport , which received CT scanners in November 2022 and announced that passengers no longer had to remove any items from their bags. 

But some industry analysts say scanning equipment is only one piece of the puzzle . “I believe that TSA and other aviation security organizations will study the results from the UK’s decision closely and carefully,” says Henry Harteveldt, an aviation expert and president of Atmosphere Research. “If behavioral profiling and other similar tools allow security organizations to potentially detect people who may pose a danger to airline crews and passengers, it may help reduce the need for measures such as the 100ml limit on liquids and the TSA’s 3-1-1 policy.”

Indeed, it seems U.S. officials plan to take it slow when considering any changes to the current TSA 3.4-oz liquid rule, which has been the international standard since it was implemented in 2006. “Computed Tomography technology produces 3-D images that can be rotated and combined with advanced detection algorithms to produce a substantial improvement in security screening,” Robert Carter Langston, TSA's press secretary, said in an emailed statement. “While we have them deployed at more checkpoints, we are years away from announcing a change to the current liquids rule.” 

Although U.S. passengers still need to pack travel-size liquids for the time being, that doesn’t mean that the security checkpoint hasn’t been seeing other improvements. Aside from rolling out more CT scanners, TSA has been deploying credential authentication technology: new ID scanners that don’t require passengers to show their boarding passes . Earlier in 2022, the agency also began accepting digital IDs from the Apple Wallet app at certain airports and testing an expansion of facial recognition to whisk travelers through even faster.

Travel Smart: Mastering the 100ml Liquid Rule for Stress-Free Journeys

A re you gearing up for your next travel adventure but dreading the airport security line? You're not alone. One of the most common hiccups for travelers worldwide is navigating the confusing world of carry-on liquids. As a travel journalist, I've seen my share of confiscated perfumes and oversized toothpaste tubes. But fear not! I'm here to turn your liquid luggage woes into a thing of the past.

• Uncover creative alternatives to liquid essentials.
• Get ready for a hassle-free journey with our expert advice.

The 100ml liquid rule can seem daunting, but it's quite simple once you get the hang of it. Let's dive into making your travel experience as seamless as possible.

Why 100ml? Unpacking Airport Security's Liquid Limit

Travel regulations, especially those concerning liquids in carry-on luggage , often leave travelers scratching their heads. The infamous 100ml liquid rule is one such regulation that has become a cornerstone of travel security procedures worldwide. But why this specific limit? Why 100ml?

This international standard was adopted primarily for security reasons , in response to increasing concerns over the potential for liquid explosives being brought aboard aircraft. The limit of 100ml per container is based on security research indicating that smaller quantities of liquids are less likely to pose a significant threat. By restricting each container to no more than 100ml, or approximately 3.4 ounces, security agencies effectively reduce the risk of harmful substances being carried onto airplanes in significant, potentially dangerous quantities.

The rule stipulates that all liquid containers must fit comfortably within a single, transparent, resealable 1-liter plastic bag. This measure not only limits the total volume of liquids each passenger can bring but also ensures that these items can be easily and quickly inspected at security checkpoints. The transparency of the bag serves a dual purpose: it allows security personnel to assess the contents without opening the bag, and it reminds travelers to consider carefully what liquids they really need to carry.

It’s important to note that the 100ml rule applies to all liquids, gels, aerosols, creams, and pastes. This includes everyday items like toothpaste, shampoo, hand sanitizers, and even food items like jams and spreads. The rule is enforced universally across most international airports, creating a consistent standard for travelers around the globe.

While it might seem restrictive, this regulation has been crucial in enhancing aviation security. Since its implementation, the 100ml rule has become a routine part of air travel, with both passengers and security personnel adapting to ensure safety in the skies. By complying with these guidelines, travelers contribute to the global effort to make air travel as secure as possible.

Understanding these regulations is key to a smooth airport experience. With a little planning and savvy packing, complying with the 100ml rule can be simple and straightforward, allowing travelers to focus on the more enjoyable aspects of their journey.

Maximize Your Liquid Allowance: Packing Tips & Tricks

• Downsize and Decant – Invest in travel-sized containers to downsize your favorite products. This not only saves space but also ensures you're within the liquid limit.
• Solid Alternatives – Consider switching to solid alternatives for shampoos, soaps, and even toothpaste. They're great for travel and exempt from the 100ml rule.
• Layer Your Bag – Organize your liquid bag by layering items for easy inspection. This can speed up your security check significantly.

Insider Hacks: Beyond the Basics

Beyond the obvious tips, there are several lesser-known strategies to maximize your travel experience.

Did you know you can request free samples of skincare and makeup from many beauty stores?

These are perfect for travel and under 100ml. Also, look for multi-use products like BB creams that can replace several items in your bag.

Unconventional Wisdom: Rethinking Travel Essentials

We often overpack, thinking we need every item from our home routine. Challenge this notion by embracing minimalist packing . It's liberating and makes for lighter luggage!

Travel Like a Pro: Deborah Green's Personal Experiences

From my travels, I've learned that being prepared is half the battle. I once had to leave behind a cherished hand cream because I overlooked the size.

Lesson learned: always check the sizes and pack accordingly. And remember, local stores exist – you can often buy essentials at your destination.

Conclusion: Embracing the Journey with Ease

Navigating the complexities of the 100ml liquid rule is a crucial aspect of modern travel. By mastering these regulations, travelers can ensure a stress-free and efficient journey , allowing them to focus on the excitement of their destination rather than the frustrations of airport security.

The 100ml rule, while initially daunting, presents an opportunity for travelers to rethink and refine their packing strategies. Embracing this challenge leads to discovering innovative travel hacks, such as utilizing travel-sized containers, opting for solid alternatives to liquid toiletries, and exploring multi-use products. These strategies not only comply with TSA guidelines but also contribute to a more sustainable and minimalist approach to travel.

Moreover, the 100ml rule underscores the importance of being prepared and informed. Regularly updating oneself on the latest travel regulations, including TSA and airline policies, is essential for a smooth travel experience. This preparation extends beyond just understanding liquid restrictions; it encompasses a broader awareness of security procedures and travel etiquette.

Travelers today seek efficiency and ease in their journeys, and adhering to the 100ml rule is a step towards achieving that goal. Whether you’re a seasoned traveler or planning your first trip, embracing these guidelines can transform your travel experience. It’s not just about following rules; it’s about evolving as a savvy traveler who is ready to tackle any challenge that comes their way.

Let's remember, travel is not just about the destination but also the journey. By mastering the art of packing and staying informed about travel regulations, we can ensure that our journey is as enjoyable and hassle-free as possible. The 100ml rule, once a source of confusion, can become a tool for empowering travelers, leading to smarter, more efficient, and more enjoyable travel experiences.

Largest Batch of Earth-size Habitable Zone Planets Found Orbiting TRAPPIST-1

TRAPPIST-1: Largest Batch of Earth-sized Exoplanets

The most studied planetary system, aside from our own solar system, lies about 40 light-years away. We've looked at the seven rocky exoplanets orbiting the TRAPPIST-1 star with ground and space telescopes like Spitzer, Kepler, Hubble, and, now, the James Webb Space Telescope.

In March 2023, the first science from the Webb telescope was released. An analysis of TRAPPIST-1b, the innermost planet, revealed its dayside temperature and found little evidence of an atmosphere .

In a press release on February 22, 2017, NASA announced the discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds–all of them with the potential for water on their surface – is an exciting discovery in the search for life on other worlds. There is the possibility that future study of this unique planetary system could reveal conditions suitable for life.

In February 2018, closer study of the seven planets suggested that some could harbor far more water than the oceans of Earth, in the form of atmospheric water vapor for the planets closest to their star, liquid water for others, and ice for those farthest away. The study pinned down the density of each planet more precisely, making TRAPPIST-1 the most thoroughly known planetary system apart from our own.

A 2021 study revealed more about TRAPPIST-1 planets. They are likely made of similar stuff, but they are different from Earth. That could mean they all contain about the same ratio of materials thought to compose most rocky planets, like iron, oxygen, magnesium, and silicon. But if this is the case, that ratio must be notably different than Earth's: The TRAPPIST-1 planets are about 8% less dense than they would be if they had the same makeup as our home planet.

Planet hop from TRAPPIST-1 e

Take a trip with the Exoplanet Travel Bureau to the fourth planet in the TRAPPIST-1 system, TRAPPIST-1 e, a world swimming in water in perpetual twilight. Its sister planets gracefully light up the sky, promising another adventure just a hop away.

Interact with the TRAPPIST-1 system in 3D

You can fly through the TRAPPIST-1 planets and see an artist's concept of the surfaces on your phone or with a desktop app. Compare each planet to Earth or Jupiter, compare the TRAPPIST-1 system to our solar system, and see how far the habitable zone extends. With the touch of a screen or the click of a mouse, you can visit the newly discovered TRAPPIST-1 system in the our Exoplanet Catalog. It contains every exoplanet discovery, powered by NASA's Exoplanet Archive, the official database used by professional astronomers engaged in exploring new worlds.

This Glittery Setting Spray Might Not Be a Gimmick

This essay first appeared on Wednesday, May 1, 2024, in  The Strategist Beauty Brief ,  a weekly newsletter in which our beauty writers share their must-tries, can-skips, and can’t-live-withouts. But we liked it so much we wanted to share it with all of our readers. If you want more first impressions of buzzy launches, quick takes on what’s trending on TikTok and Instagram, and deep dives into the week’s best beauty launches, sign up  here .  The Strategist Beauty Brief  is delivered every Wednesday.

I’m a sucker for movie tie-in makeup collections — so I knew I’d be trying  Wicked’s  One/Size beauty collaboration as soon as I heard about it. Included in the limited-edition product drop was a product I was particularly interested in, though:  a glittery version  of the brand’s  best-selling setting spray  (the spray is currently sold out, but you can sign up  here  for updates on a restock).   Longtime Beauty Brief subscribers will know I have a special interest in products that make my  skin sparkle .

For locking my makeup in place and giving it some added glow, I’ll always use a setting spray. But One/Size spray is one I’d never felt particularly drawn to. That’s because it’s a famously mattifying product, and I prefer dewy products, like the setting spray from  Iconic London . One of the things I like the most about the Iconic London setting spray is that it contains teeny light-reflecting particles that, once applied, leave a shimmering glow on the skin. That made me wonder: How shimmering could my skin look if those tiny particles were specks of glitter instead?

Holding the product ten inches away from my face (as per the instructions on the candyfloss-pink bottle), I applied a thorough coating to my finished makeup. Now, let me tell you: This stuff dries  fast.  I’m used to wafting a fan over my face to set my spray, but the One/Size setting spray had dried to a completely matte finish within a matter of seconds. I’m used to a dewy finish, so I was a little shocked, but my skin didn’t feel dry whatsoever. (If you’re on the drier side like me, though, I think the key here is good skin prep, and slightly less setting powder than usual.)

As it was drying, I noticed a really divine, fresh, light aroma from the spray — and then turned to the mirror for the true reveal. I’d been apprehensive that it might come out like glitter sprays my mum used to drench me in before dance competitions — but I didn’t need to worry. As I tilted my head from side to side, and the flecks of cool toned glitter caught the sunlight, I breathed a sigh of relief. I was definitely sparkling, but I hadn’t entered into the dreaded “This is the skin of a killer, Bella” territory.

After five or ten minutes, I’d acclimatized to the more matte feel of the setting spray, and I set off to meet my friends at the pub. As the sunlight faded, the glitter became even more obvious under synthetic lights. It was definitely noticeable — one of my friends asked if I’d put glitter on — but not so dramatic that I felt overdone. And my makeup absolutely did not budge an inch — I mean not whatsoever. I’m used to my liquid blush fading with the evening, but by the time I got home after three or four hours, I looked as freshly made up as I did when I left the house.

I’ve since played with the distance at which I apply the spray, and the effect is as you’d expect: If you go a little closer, the glitter is a little stronger. For raves and festivals, I’ll definitely be experimenting with a closer coating of the spray — I’m 100 percent going to pack it in my makeup bag for Glastonbury. But for a night out (or casual trip to the bar, depending on how OTT you like to go), this is just a great quality, gorgeous product if you’re keen on giving your makeup a little frosting, and achieving an iridescent glow.
