10 Full-Size Liquids You Can Actually Take Through Airport Security

By Rachel Chang

For the better part of two decades, we’ve limited the liquids we carry through airport security. The magic number settled upon was 3.4 ounces, or 100 milliliters, of liquid in a container—an amount that became an  international standard developed by explosives experts . 

As frequent travelers are well aware, bottles that are 3.4 ounces or less can be stashed into a single one-quart plastic bag, and each traveler is allowed one—in a rule that’s been dubbed the 3-1-1 liquids rule. Oversized liquids can still be packed, but need to go into checked-in baggage.

But as screening devices have become more savvy, there has been talk of those limits being eliminated, especially as a  recent report said the UK will scrap the rules by 2024. “The introduction of new technologies has played a significant role in how aviation security has evolved over the past 20 years, thanks to strong industry partnerships and TSA’s agility in adopting technology that enhances security and improves the passenger experience,” a TSA spokesperson says. While there’s no timeline in place yet, the agency “anticipates the limit on liquids will be lifted in the coming years.”

So in the short run, travelers still need to limit the fluids they pack in carry-ons. But, as with all rules, there are exceptions. “TSA requires additional screening to ensure the safety of these liquids,” the spokesperson says of the items. “Travelers in this group should notify security of their medically-necessary liquids.”

In general, those  exceptions need to pass a three-prong test . They need to be required during the duration of your flight or at your destination, they can’t be available at the airport in the area past security, and they can’t be available at the destination. But when it comes down to it, the  TSA says on its site , “The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.”

Here are some of the most common exceptions of oversized liquids that can be taken through security. 

Prescription liquids, creams, and gels

Medication that has been prescribed specifically for you is perhaps the most common item that qualifies as an exception. TSA recommends that it’s clearly labeled so there's no question about what is inside. “You are responsible for displaying, handling, and repacking the medication when screening is required,” the agency’s site dictates. Depending on the situation, medication can either be screened visually or with an x-ray machine. It may also be tested for traces of explosives.

In some situations where the officers aren’t able to properly screen the item, you may be asked to open the container and transfer it to an empty container to test, or possibly dispose of a small quantity. 

In cases where you would like to make sure the medication isn’t opened or X-rayed, simply inform the TSA officer. “Additional steps will be taken to clear the liquid and you will undergo additional screening procedures to include a pat-down and screening of other carry-on property,” the site says.

Liquid medications and contact lens solution

In general,  liquid medications that are not prescriptions and  contact lens solutions are limited to 3.4 ounces, but TSA does allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip,” with the caveat you must declare them to security officers first. 

Breast milk and infant formula

Passengers traveling with infants have enough to worry about on their flights—and being able to provide the little ones with the proper nourishment should not be one of those concerns. Technically, TSA categorizes  breast milk and  baby formula as “medically necessary liquids.” The child doesn’t need to be present for the exception. 

In order to expedite the process, TSA suggests—but doesn't require—that the liquids be transported in clear and translucent bottles, so that they can be screened by the Bottle Liquid Scanners. (Those in pouches may not be able to.) While there is a chance you may be asked to open them, nothing will ever be placed in the liquid. The agency also adds that the screening process shouldn't affect the formula, but if you prefer they not be x-rayed, alternative testing means can be taken.

Baby and toddler food and drinks

In addition to breast milk and formula, food and drinks for babies and toddlers are also allowed, including puree pouches. They also technically fall into the “medically necessary” category.  Water for babies is also allowed in “reasonable quantities.” 

Liquid teethers

TSA also recognizes how important teethers are to babies and has “ liquid-filled teethers ” specifically called out as an item that can be brought through the security check.

Ice, gel, and freezer packs and other accessories to medically necessary items

Ice, gel , and freezer packs that are required to keep other medically necessary items in their required cool state are also exceptions, no matter what state they are in (solid ice or liquid gel). Additionally, IV bags or other accessories to medical supplies are also allowed. 

Hand sanitizer 

In the age of the COVID-19 pandemic, one major allowance was added to the list— hand sanitizer . While they may be readily available beyond security check and at your destination, the hygiene item was added, especially for use on the plane, as some experts have said that extra precautions should be taken on airplanes and airports to prevent the spread of germs .

Until further notice, hand sanitizers of up to 12 ounces are allowed since “TSA understands that COVID-19 is at the forefront on the minds of travelers, as health officials are encouraging that individuals wash their hands frequently,” the  site says . 

Live fish in water

Assuming your  live fish in water needs more than 3.4 ounces of water, this is another exception to the rule, as long as they’re in a clear transparent containers and properly inspected by the TSA officer. 

Biological specimens 

Liquid exceptions can be made in the name of science.  Non-infectious specimens in preservative solution can be carried through if it’s for scientific research. But they’ll need to be very specifically packed.

There can be up to 30 milliliters of free liquid in a heat-sealed inner plastic bag and then no more than one liter in the outer packaging, which needs to be marked: "Scientific research specimens, 49 CFR 173.4b applies." (Specific instructions for the regulation are  here .)

Duty-free purchased items in officially sealed bags

Shopping at the airport? Those liquid souvenirs can be taken home as well, as long as they are properly sealed by the cashier in a  security tamper-evident bag (STEB). The system was “developed to allow an exemption" to liquid volume rules for items purchased at duty-free airport retailers or on board an aircraft, according to the  International Civil Aviation Organization .

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.

For more TPG news delivered each morning to your inbox, sign up for our daily newsletter .

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.

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.

Everything You Need to Know About TSA Liquid Rules

Here's what to know before you fly with shampoo, medication, or any other liquids you may need during your travels.

Dealing with airport security can be one of the more daunting aspects of air travel , from the detailed rules about what you can and can't bring on board to the long lines that often form at checkpoints.

One rule that frequently trips up travelers is the Transportation Security Administration's (TSA) 3-1-1 regarding liquids in carry-on bags . We're here to walk you through the finer details of the rule and provide helpful tips for packing liquids when you're flying.

What is the TSA's 3-1-1 rule?

In 2006, British security officials thwarted a plot to bomb an aircraft with liquid explosives carried on board. Since then, security agencies around the world have limited the amount of liquid passengers can bring through airport security.

For the TSA, which regulates travel in the United States, all liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less. All liquids must fit into a single, clear quart-size bag — passengers can only pack one of these bags in their carry-on.

The 3-1-1 designation is a simple way to remember these numbers: individual liquid containers must be 3.4 ounces or smaller, they must fit into one clear, quart-size bag, and there is only one bag allowed per passenger.

Liquids that do not comply with the 3-1-1 rule must be packed in checked bags, or thrown out at airport security. Some liquids, such as gasoline or other flammable liquids, are prohibited entirely, both in checked and carry-on bags. You can find a full list of permitted and prohibited items on the TSA's website .

If you're unsure if a specific item adheres to the 3-1-1 rule, you can always contact the TSA before your trip. "Tweet your questions and comments to @AskTSA or via Facebook Messenger , weekdays from 8 a.m. to 6 p.m. ET," TSA spokesperson Jessica Mayle tells Travel + Leisure . "You can also call the TSA Contact Center at 866-289-9673."

Are there any exceptions to the 3-1-1 rule?

The TSA does exempt some items from the 3-1-1 rule: medically necessary liquids, formula, and breast milk. You can bring more than 3.4 ounces of these liquids on board, but you may have to undergo additional security screening.

"Inform the TSA officer at the beginning of the screening process that you're carrying them," says Mayle. "These liquids are typically screened by X-ray, but TSA officers may also test them separately for explosives or concealed prohibited items. Officers may ask you to open the container and/or have you transfer a small quantity of the liquid to a separate empty container, or dispose of a small quantity, if feasible."

If you don't want your exempt liquids to be screened by X-ray, inform your TSA officer, and they will use alternative security measures to clear the items.

And that's not all. "There's an exception for hand sanitizer, which has a temporary 12-ounce limit," says Mayle. But as COVID-19 travel restrictions and protocols continue to lift, the temporary special case for hand sanitizer could change, too.

Another exception is liquids purchased after security in an airport. In domestic U.S. airports , you can bring nonalcoholic drinks and other liquid items purchased airside onto your flight. (This is not always the case in international airports.) Duty-free liquids, however, will be sealed in a tamper-safe bag before boarding — sometimes they're permitted in the cabin, and other times they may be stowed elsewhere on the plane.

Packing Tips for Liquids in Carry-on Bags

• While many products are sold in 3.4-ounce containers suitable for travel, not all of them are. Consider rebottling your liquids into travel-size, leak-proof cases.
• "Another way to save space in your quart-sized bag is to pack solid versions of products, which you can put in your luggage or carry-on bag without needing to place it in the quart-size bag," travel advisor Ateet Ahuja of Complete Getaways tells T+ L. "For example, you can bring a stick or solid version of some perfumes and shampoo bars instead of liquid shampoo."
• Buy your liquids, like shampoo or mouthwash, at your final destination. "While you'll spend a little extra, the cost far outweighs the potential of it spilling or leaking in your bag," says Ahuja.
• On that note, prepare for spills — Ahuja advises wrapping a small hand towel around your quart-size bag.
• Pack your nonliquid toiletries separately to save space in your quart-sized bag.
• Pack your liquids bag in an easy-to-access space, like an external compartment or the top of your carry-on bag. According to Ahuja, "This will save you time in the TSA line."

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

Understand these rules so you don’t get held up on the TSA security line!

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 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.

Liquids Allowed in Carry-On Luggage

Joe Raedle  /  Staff  / Getty Images

If you're taking a flight for your vacation, you need to know the quantities and types of liquids that the Transportation Safety Administration (TSA) allows passengers to bring onto an airplane in their carry-on luggage .

While good security is essential, TSA's regulations on liquid quantities certainly make it harder to take some necessary items on planes. Today’s travelers have to pay attention to exactly what they’re carrying, especially when it comes to shampoos, shaving cream, drinks, and anything resembling a fluid, as many of the TSA's rules forbid these items in certain quantities.

The TSA and airport screeners are strict about the amount and type of liquids that travelers can take with them on the plane. However, they've fortunately developed a handy guide to help passengers prepare for their trip. Known as the 3-1-1 rule for carry-on liquids, this rule states that most liquids, gels, and aerosols can be transported as long as each item is in a 3.4-ounce or smaller container and all items fit in a single one-quart plastic zip-top bag.

The 3-1-1 Rule

According to the 3-1-1 guidelines, travelers, in general, are allowed to bring on most liquids, from shampoo to hand sanitizer gels, as long as they meet the requirements of the 3-1-1 rule. Typically this means you can carry up to six 3.4-ounce bottles of shampoos, contact solution, and other liquid necessities as long as they are all contained within a zip-top bag.

You can also put liquids in your checked luggage (as long as they’re not prohibited items). However, if you do this, you should make sure the liquids are sealed really well so that they don't come up while being transported beneath the aircraft. The last thing you need on a business trip is to have your shampoos or other liquids leak all over your business suit or wardrobe. Fortunately, there are plenty of great TSA-approved travel toiletry bottles available to choose from.

Special Liquids and Larger Quantities

Travelers can also declare larger containers of selected liquids, such as baby formula or medications , at the checkpoint. Airport screeners will generally allow them in moderate quantities, and declared liquids don’t have to be in zip-top bags.

Medications, baby formula and food , and breast milk are allowed in reasonable quantities exceeding three ounces, but you'll need to declare these items for inspection at the checkpoint. Also, it's worth noting that TSA screeners do allow you to bring ice through the security checkpoint as long as it's frozen solid. So if you bring ice, make sure to dump out any water before you hit the security checkpoint.

Examples of liquids that can be in excess of the 3.4-ounce rule include:

• Baby formula, breast milk, and juice (for babies)
• Both prescription and over-the-counter medications
• Liquids or liquid nutrition for people with disabilities or medical conditions
• Specialized medical liquids like contact solution
• Frozen items, if they’re frozen solid
• Medical or cosmetic items with liquid or saline

If you’re attempting to bring one of the above items with you, the TSA requires you to separate them, declare them to a security officer, and present them for additional screening. For complete information on the 3-1-1 rule, visit the TSA website, and for a complete list of prohibited items, visit the official TSA prohibited items list.

Why the TSA Limits Liquids

While it may seem like an arbitrary rule to some, the TSA 3-1-1 Rule actually took a considerable amount of negotiation and research to implement and was developed in response to an attempted attack on an airport in the United Kingdom.

On August 10, 2006, authorities in the United Kingdom arrested a group that was planning to destroy a number of airplanes by using an explosive mixture of a sports drink and other chemicals. After the arrest, the TSA rigorously tested a wide variety of liquids to determine which should be banned outright and what quantity of common household liquids was safe for passengers to bring aboard.

The United States adopted the 3-1-1 Rule in September of 2006, and the TSA screens all arriving international flights to make sure passengers comply with domestic regulations. Other countries have since adopted the same or similar regulations in order to ensure uniform administration of safety rules around the world. Canada, China, South Korea, New Zealand, Australia, and all member states of the European Union follow the 3-1-1 Rule.

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).

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. 

Do you have any tips or tricks for packing your toiletries when traveling carry-on only?

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 Airline Liquid Limit You Need To Know Before Flying

Last Updated on December 4, 2021

Your airline should inform you about the liquid limits for flying or they will be published somewhere on your airline’s website.

But it’s not your airline that sets the rules or enforces them.

It doesn’t matter if your airline is Alaska, Allegiant, American Airlines, Delta, Frontier, Hawaiian, JetBlue, Southwest, or Spirit. All airlines have the same liquid allowance because the liquid regulations are set by the Federal Aviation Authority (FAA) and enforced at the airport by the Transportation Security Administration (TSA).

There are actually three limits that you need to know about before flying.

Let’s take a look at them now.

TSA / Airline Carry On Rules

Your carry-on bag will be inspected at the airport security checkpoint by the TSA and they will make sure you are not exceeding the liquid allowance. Your airline won’t look inside your luggage at all.

Limit A – Travel Size Containers

The first airline liquid limit is that you must pack liquids in travel sized containers. Travel sized means bottles or containers that are 3.4 ounces or less .

If 3.4 oz strikes you as a strange amount to choose it’s because that it’s equivalent to 100 ml.

It’s the size of the container that is important, not the amount of liquid remaining in the container. So you can’t bring a 5 oz bottle when there is only 3 oz remaining inside.

Refillable travel size containers are a great money saving purchase because you can just fill them up from the big bottle you have at home. Buying travel size versions of products is expensive.

I like to use a collection of bottles and containers of different sizes. There is no sense in packing 3.4 oz of liquid if you only need 1 oz for your trip. A kit like this would be perfect:

The TSA considers liquids, gels, aerosols, pastes, and anything that you can smear or spread to be a liquid.

My favourite example of this is peanut butter . Peanuts are treated as a solid, but peanut butter is considered a liquid by the TSA.

Limit B – All Containers Must Fit Inside A Quart Size Bag

The second airline liquid limit is that all your travel size liquids must be packed in a one quart size bag .

You can buy a reusable ‘ TSA Approved Toiletry Bag ’ that isn’t actually TSA sanctioned but will work anyway. Or you can use a simple resealable bag like a Ziploc plastic baggie that has the capacity of 1 quart .

You might be able to fit 6 or 7 travel size bottles in a quart size bag. If you buy a reusable one then you’ll probably fit more since they are not actually quart-sized but you’ll probably get away with it.

Limit C – Only One Bag Per Passenger

The third airline liquid limit is that you are only permitted one plastic bag per passenger . You can’t bring two liquids bags if you are bringing two suitcases. It’s 1 bag each maximum.

There is no way around the one bag rule. If you are struggling to fit all the liquids you need in one bag the best way to deal with that is to try to substitute solid versions of products.

For example, a solid bar of soap can replace shower gel.

A solid stick deodorant can replace an aerosol spray.

You can even buy solid toothpaste tablets that might suffice until you are able to visit a local shop.

My top tip is that the TSA doesn’t consider wet wipes to be a liquid .

So if your liquid product is available in a wet wipe form then the wipes will make a great substitute and free up space in your liquids bag. Makeup cleansing wipes are a good example.

These three airline liquid rules are called the 3-1-1 by the TSA:

• 3 .4 oz containers
• 1 quart sized bag
• 1 bag per person

There also a 4th restriction about the type of liquids you can pack. Let’s call it Limit D.

Limit D – No Flammable Liquids Unless They Are Toiletries

You can’t bring flammable liquids or hazmat liquids even in containers smaller than 3.4 oz unless they are toiletries.

My favourite example of this is that you can bring bug repellant that you apply to your skin, but you can’t pack an aerosol bug killer spray even if it’s under 3.4 oz because it’s flammable and not a toiletry.

The TSA defines a toiletry as something that you use on your skin.

Exceptions To The Airline Liquid Limit

The liquid limit that your airline talks about is only for getting past the TSA security checkpoint.

It’s not a limit to how much liquid you can bring on the plane, it’s a limit to how much liquid can be in your carry-on bags when you go through the screening process at airport security.

That means that if you buy any liquids after the security checkpoint then you can bring them on the plane no matter what size they are. So you can fill up your water bottle after the TSA checkpoints.

There are also a few cases where you can bring containers larger than the 3.4 oz regulations normally permit.

• You can bring breast milk, juice, liquid foods, or drinks for infants in reasonable quantities
• On international flights you can carry duty free liquids in a secure tamper evident bag
• You can bring medically necessary liquids in containers larger than 3.4 oz and you don’t need a doctors note.

If you have a container of liquid that is larger than 3.4 ounces and you think it qualifies for an exemption then feel free to place it in a separate bin at the x-ray machine for additional screening.

Airline Checked Baggage Liquid Limits

Liquids are not limited in checked bags as strictly as they are in carry-on luggage.

Only Limit D from above applies. You cannot pack flammable or hazmat liquids in checked bags because of the fire risk.

You can pack as much beer or low strength wine as you like but you can only pack 5 litres of alcohol that is between 24% and 70% ABV. Alcohol over 70% ABV is prohibited because it’s too flammable.

Lastly any toiletry aerosols that you pack in checked luggage should be in containers smaller than 18 oz and you are only allowed to pack 70 oz per person of toiletry aerosols in checked luggage.

The Bottom Line

The liquids rule that your airline talks about is actually the FAA carry-on liquids rule that will be enforced by the TSA at the airport.

There are 3 limits or restrictions. Containers can be 3.4 oz maximum . They all need to go in a one quart size bag . And you can only bring one liquids bag per person.

There are exceptions to the regulations for medically necessary liquids or liquids for babies and infants.

Carry-On Baggage

1 Carry-On Bag

1 Personal Item

Each passenger flying with Delta can bring 1 carry-on bag and 1 personal item free of charge (such as a purse, laptop bag or item of similar size that will fit underneath the seat in front of you). If you plan to bring roll-aboard luggage or a large bag to store in the overhead bin, you can find size information , Go to footer note below. Note: Carry-on bag exceptions apply for passengers traveling with an infant-in-arms and for passengers traveling with pets in the cabin .

When packing, please remember that flight attendants are unable to proactively assist customers placing carry-on baggage into overhead bins, with certain exceptions. In addition to keeping customers and crew members safe and healthy, this change also protects flight attendants by decreasing the likelihood of injury caused by repetitive lifting.

Review the following guidelines for approved personal items that you can bring, including items that are free to carry on like child safety seats.

Approved Personal Items

Bringing a personal item? Pick an item like this or of a similar size to store beneath the seat in front of you during your flight.

• 1 purse, briefcase, small backpack, camera bag or diaper bag
• 1 laptop bag (computers cannot be checked, unless directed to by security)
• 1 item of similar or smaller size to those listed

Free Items to Carry On

These items are free to carry on your flight, in addition to your usual carry-on items. Flight attendants can assist you with larger items, like strollers.

• A jacket and/or umbrella
• Food or drink purchased past the security checkpoint
• Duty-free merchandise
• Special items like strollers , wheelchairs , child safety seats or assistive devices , like crutches

Whether it’s a duffel for an overnight trip or a roll-aboard bag for a much longer stay, arrive knowing that you can easily store your bag in an overhead bin. The faster you can stow your bag, the faster your flight will be on its way.

Carry-On Size Restrictions

Make sure your bag fits this size or reference size check displays located at ticket counters and gates.

• Combined length + width + height of baggage must not exceed 45 linear inches (114 cm)
• Individual length, width and height measurements may not exceed 22” x 14” x 9” (56 cm x 35 cm x 23 cm) respectively
• These measurements include any handles or wheels, but do not apply to small musical instruments that fit in the overhead or under-seat space

Carry-On Weight Restrictions

The following locations have specified weight restrictions for carry-on bags:

• Singapore, Singapore – Changi International Airport ( SIN ) carry-on should not exceed 15 lbs (7 kg)
• Beijing, China – Beijing Capital International Airport ( PEK ) Civil Aviation Administration of China (CAAC) requires that domestic hand carry bags should not exceed 10 kg. Individual carrier rules apply for international flights
• Shanghai, China – Pudong International Airport ( PVG ) carry-on should not exceed 22lbs (10 kg)
• If your bag doesn’t fit or an exceptionally-full flight is short on overhead bin space, a flight attendant or gate agent can assist you by checking your bags at the gate.
• Passengers traveling on Delta Connection flights, including flights with 50 seats or less, are only permitted to carry personal items on board the aircraft due to limited overhead space. Personal items must be able to fit securely under the seat in front of the passenger or overhead bins. Due to crowded flights, some carry-on bags may be gate checked, free of charge, during the boarding process and returned upon deplaning. Please ensure that a pink Gate Claim/Planeside tag is securely attached to the carry-on item. Assistive devices are not subject to this restriction.
• If you need information about potentially hazardous or irregular items, like knitting needles or razors, please consult the TSA for updated guidelines .
• Airline Partner Notice: Our SkyTeam and codeshare partners may have different guidelines and restrictions on certain flights, so be sure to check before you check in.

While many things are allowed in your carry-on and personal item when you travel, be sure to consider things that are limited for your safety. Most countries restrict the size of containers with liquids, gels, aerosols and pastes — even in partially empty containers during security. Pack ahead of time and place larger liquid items in your checked luggage.

• Limit liquids, gels, aerosols and pastes items to a maximum of 3.4 ounces or 100 milliliters
• Place all items in one single quart-size, zip-top bag of clear plastic
• At security, remove your quart-size bag and place it in a bin

Liquids, gels, aerosols and pastes include anything like beverages, creams, hair gel, hair spray, shampoo, suntan lotions, toothpaste or any item of similar consistency. Special provisions are usually made by the TSA for necessary items such as medication, breast milk, and juice or formula for infants - which can receive a special screening for your convenience.

Review TSA Guidelines

Some countries have a program that lets you purchase duty-free items, which are placed in specially sealed bags by the vendor. You can then travel within that country or region with your item in your possession or in your carry-on.

If your travel takes you through a security check-in in a country that does not recognize the same program, you may or may not have the opportunity to place the item in your checked baggage. If you are unable to place the item in your checked baggage, it may be confiscated.

For specific guidelines, visit the U.S. Transportation Security Administration , the United Kingdom’s Department for Transport or the European Union’s European Commission .

How many bags may I carry on?

You may bring one carry-on item onboard the aircraft, plus one personal item. See our carry-on allowance for further information.

Passengers travelling on Delta Connection flights with 50 seats or less are permitted to carry personal items onboard the aircraft. Due to limited overhead and under seat space, larger items will be tagged with a pink Gate Claim/Planeside tag and loaded in the cargo bin. These bags will be returned to the passenger upon deplaning.

All carry-on items must meet Federal Aviation Administration (FAA) regulations and may not exceed 22" x 14" x 9". The FAA mandates that all carry-on items fit under a seat or in an enclosed storage compartment.

Our gate or flight personnel may need to further limit the amount of carry-on baggage for a particular flight, depending on the cabin storage capacity of the plane and the expected number of passengers.

Are carry-on items included in Delta's Baggage Liability?

We do not assume liability for unchecked items unless they are given to our personnel for storage during the flight or otherwise delivered into our custody for travel.

How Big is a TSA Approved Quart Size Bag For Carry on?

The TSA has specific requirements for what can be carried on an airplane in terms of both size and type of travel-size containers.

One item that is often question is how big is a quart size bag for carry on .

Many people that air travel frequently want to know how to best pack their carry-on baggage to avoid any delays or hassles at the airport.

There are current TSA regulations that have very specific guidelines about what can and cannot be carried on an airplane , and one item that is often questioned is the quart size bag.

This bag must meet certain size requirements in order to be allowed through airport security.

What exactly are those size requirements? And how can you make sure that your bag meets them?

Read on for everything you need to know about the TSA’s quart size bag guidelines.

Quart Size Bag Guidelines

The definition of a quart size bag is a clear, plastic, zip-top bag that has approximate dimensions of 7 x 8 cubic inches.

This is the maximum size bag that is allowed through security. Anything larger than this will not be permitted.

In terms of what can be carried in the quart size bag , each passenger is allowed to bring one quart-sized bag of liquids, aerosols, gels, creams and pastes in their carry-on bag and through the checkpoint.

All liquids, gels and aerosols must be placed in a single, quart-sized, clear plastic, zip-top bag. Only one item per bag is allowed.

Make sure to declare all liquids, gels and aerosols at the security checkpoint for inspection.

There are a few exceptions to the TSA’s quart size bag guidelines. Medications, baby formula/food and breast milk are allowed in reasonable quantities exceeding 3.4 ounces (100 milliliters).

Additionally, these items must be declared to the TSA officer at the checkpoint for inspection.

If you have larger containers that are half-full or less, you may pack them in your carry-on bag .

Empty containers that previously held liquids are allowed in carry-on bags.

In order to make packing your quart size bag easier, remember the 3-1-1 rule.

This rule states that each passenger is allowed to bring one quart-sized bag of liquids, gels, creams and pastes in their 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.

Therefore, all liquids, gels, and consols must be placed in a single, quart-sized, clear plastic, zip-top bag. Only one bag per person is allowed. The bag may be placed in a carry-on bag or in your checked bag.

While there are numerous sizes of baggies and types the approximate dimensions of a quart-size bag should be 7″ x 8″.

Here are a few examples of TSA-approved quart size bags:

• Ziploc brand bags ( the most popular brand)
• Hefty brand Slider Storage Bags
• Glad brand Slide Lock Steamer Bags

TSA Liquids Rule

The TSA liquids rule is in place to ensure the safety of all passengers on an airplane.

This rule states that each passenger can bring liquids only if they are in containers that hold 3.4 ounces (100 milliliters) or less and all of these containers fit into 1-quart bag.

A great way to add maximum space is to use a smaller container for your liquids and only bring as much as you need.

Items Permitted in Quart-Sized Bags

There are certain items that are permitted in quart sized bags. Any of the following items can be found in a travel size that meets TSA rules.

• Baby formula, baby food, breast milk,and juice for infants or toddlers
• All medications (liquids, gels, creams and pastes)
• Solid food items
• Contact lens solution
• Stick deodorant
• Body lotion
• Liquid lipstick
• Cream/gel blush
• Peanut butter
• Lip gloss or lip balm
• Nail polish
• Hand sanitizer
• Liquid foundation
• Carry-on toiletries

There are some types of deodorant that are not permitted so be sure to check before packing.

For the amount of liquid you have each one can be placed in 3.4 oz bottles and a 1-quart capacity clear plastic bag.

Containers of liquids should be tightly sealed and placed in the correct size Ziploc bags. You can also place your liquids bag in your toiletry bag for easier access.

Items Not Permitted in Quart-Sized Bags

However, there are certain items you can not bring in your quart-sized bag, even if they are 3.4 ounces (100 milliliters) or less. These include:

• Pepper spray
• Cremes with a solid phase
• Non-solid food
• Sharp objects uncovered
• Open flames (lighters, matches)

Liquid Rules For Frozen Items

Frozen liquids are only permitted if they are still frozen when you reach the TSA security checkpoints. They have to be presented to TSA officers still frozen and in a clear bag .

If the frozen liquid or ice packs becomes slushy, melted, or has liquid at the bottom it must meet 3-1-1 liquid TSA approval.

If you are unsure if your frozen item will last through the security screening process you can check out TSA’s official page for more information.

What Happens if Your Personal Item Doesn’t Meet TSA’s Limits

If you try to bring a clear quart-sized baggie filled with items that exceed 3.4 ounces (100 milliliters), the TSA will most likely confiscate those items or require additional screening.

You will need to put your quarter of a gallon of toiletries in a separate bin for them to check.

There are a few ways around this, however. You can ask the TSA officer if you can empty out your quart-sized bag and only bring the items that are 3.4 ounces (100 milliliters) or less in your carry-on luggage.

You can also put your liquid product in a checked bag, as long as they’re declared and placed in a secure, tamper-evident bag.

If your checked bag happens to be over 50 lbs. you will have to pay an additional cost.

Keep in mind that even if an item is under 3.4 ounces (100 milliliters), it may still be prohibited by the TSA.

Be sure to check their website before packing any liquid cosmetics, powder-like substances, and self-defense sprays in your carry-on or checked travel bag.

How to Determine the Volume of Your Containers

When packing your quart-sized bag, it’s important to make sure that all of your containers fit within the prescribed 3.4 ounce (100 milliliter) limit.

The easiest way to do this is to check the label on each container. Many travel-sized toiletries are clearly marked with their volume in ounces or milliliters.

If you’re unsure about the right size of your container, you can also fill it with water and use a kitchen measuring cup to determine how many ounces or milliliters it holds.

Simply pour the water into the container until it reaches the top and then measure it with the cup.

Remember that you are only allowed one quart-sized bag per person. This bag must be placed in your carry-on bag or checked bag.

Packing Your Quart Size Bag

Now that you know what can and cannot be placed in a quart size bag, it’s time to start packing! Here are a few tips to help you get started:

• Make sure all containers fit comfortably in the quart size bag with the zip closed. The bag should not be overly full or bulging.
• Pack items that are similar in nature together. For example, place all liquid items together, all gels together, etc. This will make it easier to find what you’re looking for and declutter your bag.
• Place your quart size bag at the top of your carry-on bag so that it is easily accessible. This will help speed up the security process.

What Not To Use as Your Quart-Sized Bag

Quart-sized bags are a requirement to fly with a carry-on bag for any liquid container smaller than 3.4 oz. There are some bags that won’t get by.

For example, a sandwich bag is too flimsy and will tear, and a gallon bag is too large.

The TSA also prohibits any bag that has been previously used to carry liquids, so make sure your bag is clean and dry before packing your liquids.

For a half-decent substitute for a quart-sized bag, try using a ziplock freezer bag. Just make sure it’s clean and dry before packing your liquids.

When in doubt, it’s always best to err on the side of caution and bring a quart-sized bag that meets TSA guidelines.

This will help ensure a smooth and hassle-free security experience.

What Type of Carry-On Bagge is Approved?

The TSA has a few requirements for carry-on bags. First, the bag must be small enough to fit in the overhead bin or under the seat in front of you.

Secondly, the bag must be able to stay closed and locked throughout the duration of your flight.

Here are a few examples of bags that are typically allowed as carry-ons:

• Rolling suitcase
• Hand luggage
• Diaper bags

Remember, you are only allowed one carry-on bag and one personal item per person.

Additionally, be sure to check with your airline to see if they have any additional restrictions on carry-on luggage.

Additional Guidelines to Follow

In addition to adhering to the TSA’s quart size bag guidelines, there are a few other general guidelines to follow when packing your carry-on bag .

Furthermore, all liquids, gels, and aerosols must be placed in a single, clear, quart-sized bag.

Only one item per bag is allowed. The bag may be placed in a carry-on bag or in your checked bag.

Additionally, always make sure to declare all liquids, gels, and consols at the security checkpoint for inspection.

All electronic devices must be placed in a bin for X-ray screening bin. Make sure to remove all food items from your carry-on bag before sending it through the X-ray machine.

Tips For Traveling With Liquids

• Purchase travel-sized containers : This will help you to stay within the TSA’s 3.4 ounce (100 milliliter) limit.
• Pack your liquids at the end of your packing process: This way, if any of your containers leak, they will not ruin your other belongings.
• Make use of empty space in your quart-sized bag : Fill up any empty space with items such as socks or jewelry to prevent your liquids from moving around and potentially leaking.
• Use a hard sided carry-on bag: This will help to protect your belongings in case of any spills or leaks.

By following these tips, you can make traveling with liquids a breeze.

Final Thoughts

In conclusion, a general rule to make sure you have the perfect size resealable bag is to check the TSA website.

In the United States, the TSA has set guidelines for what you can and cannot bring on an airplane .

They also have a helpful chart that outlines the maximum container sizes for liquids, gels, and aerosols that are allowed in both checked and carry-on bags.

The good news is there is also a TSA precheck line that you can use if you have certain items in your quart size bag.

This is a good idea to help you to speed through the security process without having to remove your liquids and gels from your bag.

How Big Is a Quart-Sized Bag With TSA Approved Liquids

Traveling by air can be a pleasurable and delightful experience. However, it can induce stress and become challenging, mostly if flying for the first time. Aside from booking accommodations and flights and scheduling itineraries, there is also the duty of packing. Understanding what cannot be brought and what to bring in carry-on baggage can ease the airport’s annoyance and save time.

It could entail knowing the liquids permissible on the flight and how to pack them suitably. Also, awareness of how big is a quart-sized bag is vital. Many travel enthusiasts and those who routinely travel by air have heard and know how the 3-1-1 rule applies when packing liquids.

Quart-Sized Bag and Its Dimensions

As per TSA requirements, a quart-size bag is a transparent plastic zip-top bag that air passengers can use to pack their travel liquids or toiletries when flying. Its measurement is approximately 7 inches in length and 8 inches in width (7″ x 8″), a volume of 1 quart. Any items placed inside this bag must fit within the designated size and be able to be fully closed by the traveler.

The standard sizes of quart-sized bags ensure manageable inspection and uniformity at airport security checkpoints. The quart baggie’s transparency allows the airport’s security team to easily screen contents inside or remove them for further inspections if desirable. Thus, it is crucial to avoid using patterned or colored bags, which may create confusion during the checking process.

Utilize resealable plastic bags for TSA screening process  convenience, durability, and versatility. Smaller bags may be ideal for those who travel occasionally, but finding the ones that meet the dimension limits can be challenging. Also, a recyclable quart-size bag could be efficient as you can use it numerous times before getting a new one or disposing of it after flying.

Choices Used for Quart-Sized Bags

You may doubt the quart-sized bag material needed when traveling by air. One of the most easily accessible and popular options is a clear Ziploc bag . However, there are also more durable choices like reusable silicone bags or clear toiletry pouches that you can order from most travel online or physical stores.

You can use a zip-top closure bag primarily made of sturdy plastic to ensure liquids or toiletries do not fall if a bag is damaged when traveling. These bags have strong seams for extra safety of your items and can prevent leakage or tears. Depending on how big a quart-size bag is, these seams ensure your toiletries or liquids are intact as you travel, protecting them from potential spills or leaks.

Overview of the 3-1-1 Rule

Almost all airports around the globe follow this directive, but it is always essential to confirm your particular state’s aviation security rules or airline protocols. Not obeying these guidelines can lead to your liquid’s seizure, having them rejected, or delaying your travel. Thus, as per these directives, it is vital to pack your liquids whenever traveling by air.

Allowed Types and Amounts of Liquids in a Quart Sized Bag

As mentioned earlier, airports have strict protocols concerning what toiletries and liquids passengers can bring when flying. They can only bring restricted extents of liquids in their carry-on baggage as per the 3-1-1 rule.

TSA-accepted liquids or toiletries can encompass toothpaste, conditioner, shampoo, and other personal care substances. Also, aerosols, creams, and gels are TSA-approved. These belongings should collectively fit into the quart-sized bag and each in a vessel of 3.4 ounces or less.

Below is a list of common liquids and toiletries that are allowed in a quart-sized bag:

• Shaving cream
• Nail clipper

Measuring the Size of a Quart Sized Bag

You can utilize standard gauging tools like measuring tape or a ruler to ensure your quart-sized bag abides by TSA protocols. Accurate dimensions can lessen potential inconveniences and save time, guaranteeing a tension-free security check. A measuring tape or ruler will precisely measure 8 x 7 x 1 inches, the usual dimensions obligatory for a quart-sized bag.

Alternatives to Quart-Sized Bags

For travelers unwilling to pack their belongings using a quart-sized bag, there are alternatives for bringing liquids on board. As previously said, this entails using travel-sized belongings or checked baggage that adheres to TSA rules. Most of these travel-sized liquids or toiletries already come in transparent vessels, eradicating the necessity for quart-sized bags.

But you should be attentive to double-check their dimensions so they do not exceed the prearranged 3.4 ounces. Below are major alternatives to transporting liquids and toiletries in quart-sized bags:

• Stasher silicone bags or containers
• Reusable sandwich bags
• Beeswax wraps
• Reusable lunch bag

Tricks and Tips for Packing a Quart-Sized Bag

To ensure efficient packing, properly organizing your quart-sized bag is essential. Consider these tips and tricks when organizing your quart-sized bag.

• Separate Items Into Groups

• Squeeze or Roll Some Items Into a Smaller Container

Another excellent way to maximize space is by squeezing or rolling items like toiletries or toothpaste into smaller vessels, like contact lens cases. These belongings can be disposed of if necessary or recycled after the trip.

• Utilize Travel Sized Bottles

You may also utilize travel-sized bottles, which are ideal for shorter journeys and can be refilled. It also allows passengers to carry their favorite products without surpassing the quantity permitted.

Traveling can be a thrilling and fun experience, and understanding the limitations of liquids and toiletries in quarts baggage can help lessen any unnecessary mistakes. Recognizing and adhering to TSA rules concerning quart-sized bags is essential in making your travel smooth and avoiding airport delays.
