Arrival Appointment   What time are you planning on arriving at the port terminal on embarkation day? Select an arrival time and we'll save you a place in line. The time you select applies to everyone in your stateroom. Guests who arrive early will be asked to wait until their designated arrival window.   

STEP 4 - ONBOARD EXPENSES Carnival operates a cashless system onboard - all guests must be added to an expense account for onboard services and purchases, even if they are not given charging privileges. Since the onboard currency is the US Dollar, all monetary transactions on your onboard account (i.e, billing, charges, disbursements, etc.) are managed in USD.

• Credit or Debit Card: Open your onboard expense account (billed In USD) using any major credit or debit card. We accept: Visa / MasterCard / American Express / The Discover Card / JCB / Diner's Club

Throughout the cruise, incremental holds will be obtained as needed, applied by your card's issuing bank. If any payment is given to replace credit/debit card previously provided, the hold will remain on your account, as determined by your card's issuing bank, which will reduce the amount of funds available on your credit/debit card.  
• If you are traveling with minor children under 18 years of age, you may enter a spending limit in the field by their name.
• In order to complete your minor's booking, they will need to be added to an adult's onboard expense account but do not necessarily need to be given charging privileges. Please include any applicable minor in your own booking.

This page provides Terms and Conditions about the cruise. This information should be reviewed thoroughly. Each adult traveler must accept for themselves and their minor children, but cannot accept for other adults. Any passengers that don't complete this section will need to visit the check-in desk during embarkation to accept these terms.  To complete your online check-in, you must agree to the following cruise ticket contract. 

• Cruise Ticket Contract: Guest must scroll through the cruise ticket contract and review thoroughly. Guest will certify that he/she is an adult with full legal authority to enter into this cruise ticket contract for themselves and/or on behalf of their minor guest(s) selected.

Once the Cruise Ticket Contract has been accepted, this completes the Online Check-in process. This is indicated by the guest name(s) appearing in g reen and the prompt will read 'This guest has completed Online Check-in'. Why is this important? Completing this process before you arrive at the port will make the boarding process even easier. Once your Online Check-in is complete, you'll be able to print your boarding pass, luggage tags and even additional documents from home, to save you time when boarding.

If you’re new to TSA PreCheck or Global Entry, you may be wondering what a Known Traveler Number (KTN) is, how it works, and why there’s a KTN box when booking flights, but there isn’t one for your TSA PreCheck or Global Entry number. Here’s what you should know about your KTN.

What Is a Known Traveler Number?

Your Known Traveler Number is your membership number with a Trusted Traveler Program. This number is what allows you to access TSA PreCheck security lanes and Global Entry lanes (depending on which Trusted Traveler Program you join).

How To Get a Known Traveler Number

To acquire a Known Traveler Number, you must participate in one of the Trusted Traveler Programs. These are:

• Global Entry
• TSA PreCheck

Global Entry and TSA PreCheck are by far the most popular options in the U.S. The NEXUS and SENTRI programs also provide a Known Traveler Number, though these programs are much less commonly used in the U.S.

Credit Cards That Reimburse for Global Entry, TSA PreCheck, and/or NEXUS Application Fees

Many premium credit cards will reimburse you for the application fee for either Global Entry or TSA PreCheck (including American Express, Capital One, Chase, and Citi, which all provide cards that offer an application fee reimbursement).

Since several cards offer this benefit, consider the other benefits of your credit card options before you choose one. Look at the points they earn, trip delay protection, purchase protection, elite status, or airport lounge access.

If your priority is earning tons of valuable (and transferable!) points, you might choose the Chase Sapphire Reserve card . It earns 5x points on air travel and 10x points on hotels and car rentals when you purchase travel through Chase Travel, 10x points on Lyft (through March 2025), 3x points on all other travel, and it comes with a Priority Pass Select membership for lounge access. You’ll also receive a $300 travel credit that is automatically applied to your first $300 in travel purchases each cardmember year (this includes taxis, Uber , Lyft , train tickets, flights, hotels, and more).

If airport lounge access and elite status are your top priorities, the Amex Platinum card and Amex Business Platinum card provide world-class lounge access , including Centurion Lounges and Delta Sky Clubs (when flying Delta), on top of a Priority Pass Select membership upon enrollment. Cardholders also receive elite status with both Hilton Honors and Marriott Bonvoy upon enrollment. To top it off, you’ll earn 5x Membership Rewards points when booking flights directly with an airline.

And for travelers who value simplicity in earning and redeeming their rewards along with a reasonable annual fee, consider the Capital One Venture X card . It earns 2x Capital One miles on all purchases and comes with the lowest annual fee among the most popular premium credit cards.

Whichever card you choose, all you have to do is use it to pay for the Global Entry or TSA PreCheck application fee, and you’ll automatically be reimbursed.

How To Find Your Known Traveler Number

Hot Tip: You can find your PASSID  (also known as your Known Traveler Number) on the back of your Global Entry, NEXUS, or SENTRI card.

If you only have TSA PreCheck, log in to the Trusted Traveler Program website to access your PASSID/Known Traveler Number. If you lose your Global Entry, NEXUS, or SENTRI card, you can use the Trusted Traveler Program site to find the number.

How To Add Your Known Traveler Number to Bookings

While it might not be apparent at first, you’ll be happy to know that your TSA PreCheck or Global Entry number is, in fact, your Known Traveler Number. Simply enter your Known Traveler Number in the appropriate field when booking your flight. This can also be done later — even at the check-in desk at the airport.

The vast majority of the time, you do not need to carry your Global Entry card to access the airport’s TSA PreCheck or Global Entry lanes. That said, there have been some recent reports of travelers being asked to show their physical card. This appears to happen most at airports that allow travelers with Global Entry to preclear security, especially for flights departing from Canada. It also may happen when entering the U.S. by car via NEXUS or SENTRI lanes.

Hot Tip:  Unlike when returning from most countries, if you want to access Global Entry lanes when returning from Canada, you will need your physical Global Entry card with you.

Global Entry or TSA PreCheck: Which One Is Right for You?

As anyone who’s been through airport security knows, it can be a frustrating hassle. To expedite the screening process  at many U.S. airports, TSA PreCheck access provides a much better experience. If you are returning to the U.S. from an international destination, Global Entry can make getting through customs a breeze.

If you mainly travel within the U.S., you might think that you only need to get TSA PreCheck — this is understandable, considering the fee is $78 compared to $100 for Global Entry.

However, a Global Entry membership also provides access to TSA PreCheck. When you account for the application fee reimbursement offered by several credit cards, why wouldn’t you go ahead and get Global Entry? With the right card, the impact on your wallet is the same — neither should cost you a dime!

By getting Global Entry, you can enjoy a quicker security experience when boarding flights in the U.S. If you decide to travel abroad, you can take comfort in the fact that returning to the U.S. will be easy.

Hot Tip:  If you have additional questions, don’t miss our piece on the top Global Entry FAQs and TSA PreCheck FAQs . 

Final Thoughts

Airports are becoming busier by the year, so having access to TSA PreCheck and Global Entry is vital for quicker and smoother security screenings. With so many credit cards offering to reimburse you for the application fee, there is no excuse not to have a Known Traveler Number.

Whether you get TSA PreCheck or Global Entry, you’ll be all set for a better airport experience — just enter your PASSID/Known Traveler Number when booking your flight.

Frequently Asked Questions

How do i know if i have a known traveler number.

If you have applied for and been approved for Global Entry, NEXUS, SENTRI, or TSA PreCheck, you have a Known Traveler Number. It is your membership number from one of these Trusted Traveler Programs.

Can you add a Known Traveler Number after booking your flight?

Yes. If you forget to add your Known Traveler Number at the time of booking, you can add it later. This can be done online or at the check-in desk at the airport. We recommend doing it online before checking in.

Why isn't my Known Traveler Number working?

If your Known Traveler Number isn’t working, the likely causes are:

• You, a travel agent, or reservations agent entered the number incorrectly

Where do I find my Known Traveler Number on my Global Entry card?

Your Known Traveler Number can be found on the back of your Global Entry card. It is your PASSID number.

If you have NEXUS or SENTRI, your PASSID number will also be found on the back of your card.

How long is a Known Traveler Number good for?

Your membership with a Trusted Traveler Program lasts 5 years. At that point, you will need to renew your membership and pay another fee. Don’t forget to use a credit card that will reimburse you for the fee!

Known Traveler Number program: What is it, and should you get 1?

Editor's Note

When you travel, there are a few pieces of information you probably like to keep handy, including your frequent flyer number, your passport number and your trip confirmation number.

However, another number comes into play if you have TSA PreCheck or Global Entry : your Known Traveler Number. It's an important number that ensures access to the TSA PreCheck lanes .

Here's what to know about getting a KTN, how to find it and how to ensure it's attached to your flight reservations.

What is a Known Traveler Number?

A KTN is a nine-digit code each TSA PreCheck and Global Entry member receives from the U.S. Department of Homeland Security upon approval for one of those two programs. Members of a couple of other Trusted Traveler programs get a KTN as well.

The code may be a combination of both letters and numbers. It's your identification number that proves you're a member of one of these programs and shows that you are eligible to use the TSA PreCheck lanes at U.S. airports.

Travelers with a KTN have gone through an application and screening process , and they are known and recognized as travelers by the U.S. government.

Should you apply for a Known Traveler Number?

Getting a KTN is helpful for air travel because if you have one, it means you're a member of a program that gets you shorter wait times.

A KTN is your key to access the TSA PreCheck lanes. These lanes typically have shorter lines and allow members to undergo a less intrusive screening process than the standard lanes. About 99% of TSA PreCheck customers wait 10 minutes or less at security, according to the Transportation Security Administration.

There are several ways to get a KTN through different Trusted Traveler programs run by the DHS. Each program requires travelers to submit an application and go through an interview process. Those interviews generally occur in person at enrollment centers for first-time applicants, with many enrollment centers located at airports. The government is allowing virtual interviews for certain applicants, often those seeking to renew their membership.

Each program that provides travelers with a KTN has a fee, and memberships in all programs are valid for five years. Many credit cards also offer application fee credits for Global Entry or TSA PreCheck .

TSA PreCheck

If you've applied for TSA PreCheck, gone through the screening process and received confirmation of your approval into the program, you'll receive a KTN from the government.

TSA PreCheck offers a fast-tracked security experience for its members. When going through the TSA PreCheck lanes, you generally won't have to remove your shoes, take laptops or liquids out of your bag, or go through the full-body scanner.

The application fee is $78 for first-time applicants.

Global Entry

If you've received your TSA PreCheck membership by applying for Global Entry, you'll receive your KTN through your Global Entry membership.

Global Entry is a U.S. Customs and Border Protection program that allows travelers designated as low-risk by the U.S. government to use faster customs lines when returning to the U.S. from abroad. Members also get access to TSA PreCheck.

The fee for an application to this program is $100.

If you're planning to travel internationally and within the U.S. multiple times in the next five years, Global Entry is probably your best bet since it gets you expedited screening both at customs and at TSA checkpoints for only $22 more than a standard TSA PreCheck membership.

Nexus and SENTRI

The DHS has two other Trusted Traveler programs for travelers entering the U.S. from Canada and/or Mexico. Nexus and SENTRI also provide members with TSA PreCheck access and, thus, a KTN.

Nexus allows pre-screened travelers to use expedited processing when entering the U.S. from Canada by air or land. The fee for this program's application is $50.

SENTRI allows pre-screened travelers expedited entry into the U.S. from Canada and Mexico by air, land or sea. The application fee for this program is $122.25.

How do you add a Known Traveler Number to your travel bookings?

Once approved for TSA PreCheck, Global Entry, Nexus or SENTRI, you'll have to follow one additional step to ensure "TSA PreCheck" is printed on your boarding pass: You have to attach your number to your airline profile.

If you're just looking to attach your number to a single reservation, you can typically do this when filling out your personal information at checkout when booking a flight. However, we recommend always flying with a frequent flyer account to earn miles .

If you have a frequent flyer account, you can attach your KTN right to the personal information section of your airline profile. Once you do this, your KTN should be automatically added to each booking you make with that airline, as you include your frequent flyer number on the reservation. You typically can add your KTN to an existing reservation, too.

What to do if you forgot to add a KTN to your flight

If you already booked a flight and forgot to add your Known Traveler Number to your reservation, don't fret. You should be able to easily pull up your reservation and add your KTN.

Go to the airline's website or mobile app. Pull up your reservation using the confirmation number (or record locator) the airline gave you when you booked your trip. Then, go to the traveler information section. There should be a line that says "Known Traveler Number," "KTN" or "Secure Traveler Information." That's where you put your KTN.

If you've already checked in for your flight and downloaded your boarding pass, you may need to re-download the boarding pass to see "TSA PreCheck" appear.

Where can you find your Known Traveler Number?

The time when you'll most likely need your KTN handy is when booking a flight or updating your airline profile. This goes for new members of TSA PreCheck, Global Entry, SENTRI or Nexus, as well as existing members who might be flying with an airline for the first time since joining one of those programs.

With all the numbers, passwords and accounts we have to keep track of in our lives, it's easy to lose your KTN ... and most of us probably don't know our number by heart. Fortunately, there are a few ways to locate it.

If you're a standard TSA PreCheck member looking to track down your number, you can use this page from the DHS to put in your personal information and look up your number.

If you received your KTN through the Global Entry program, you have a couple of options. If you have your physical Global Entry card, check the backside. Your nine-digit "PASSID" is your KTN; it may start with "15," "98" or "99."

Another way to locate your Known Traveler Number is to log in to your Global Entry or other Trusted Traveler Program account. There, you should be able to see which program you're enrolled in, as well as your membership number/PASSID, which, again, is your KTN. You should also be able to see when your membership expires.

An additional option for tracking down your number is to check your frequent flyer account for an airline you've recently flown with. If your membership in one of the Trusted Traveler programs is active and you've used TSA PreCheck before, odds are your KTN is on file with one or more airlines you regularly fly.

For this option, you'll need to go to your airline profile. If your KTN is in your profile, you should see it listed under your personal information.

Bottom line

A Known Traveler Number is a code that gets you into the TSA PreCheck lane. It's how the airline and government recognize a trusted traveler who is a member of TSA PreCheck, Global Entry or other similar programs.

Keep your number handy and add it to your airline profile. If you're not a member, consider enrolling in one of these programs that gives you a KTN and makes your trip through the airport less of a hassle.

What Is a Known Traveler Number, and What Do You Do With One?

PhotoAlto / Getty Images

A Known Traveler Number (KTN), also called a Trusted Traveler Number, is a number issued by the US Transportation Security Administration ( TSA ), Department of Homeland Security (DHS), or Department of Defense (DoD). This number indicates that you have undergone a pre-flight background check or other screening before checking in for a flight.

Adding your Known Traveler Number to an airline reservation greatly increases your chances of being able to use the TSA's PreCheck security screening lanes at participating US airports. Your KTN also permits you to take advantage of expedited customs processing at select airports if you are a Global Entry member.

How Can I Get a Known Traveler Number?

The easiest way to get a KTN is to enroll in either the PreCheck or Global Entry program. If your application is approved, you will receive a KTN. A Global Entry KTN is linked to your passport information, while a PreCheck KTN is connected only to the personal information you supplied when you enrolled. Participating airlines may offer their frequent flyers PreCheck status. The airline will assign these travelers a KTN as part of that process. Active duty military personnel may use their DoD identification number as their KTN.

You may also apply for PreCheck or Global Entry on your own. US citizens pay $85 for a five-year PreCheck membership or $100 for a five-year Global Entry membership. (Tip: The nonrefundable fee must be paid whether or not you are approved for PreCheck or Global Entry.) If your travels frequently take you outside the US, Global Entry might be a better option for you because it not only provides you with a KTN but also gives you access to faster customs processing access at certain airports.

How Do I Use My Known Traveler Number?

If you received your KTN through the TSA's PreCheck program, you should add it to your reservation record every time you book a flight on a participating airline. If you make a flight reservation through a travel agent, give the agent your KTN. You can also add the KTN yourself if you reserve your flight online or by telephone. 

Participating airlines, as of this writing, include:

• Alaska Airlines
• All Nippon Airways
• Allegiant Air
• American Airlines
• Aruba Airlines
• Asiana Airlines
• Austrian Airlines
• Azul Airlines
• Boutique Airlines
• British Airways
• Brussels Airlines
• Cathay Pacific Airways
• China Airlines
• Condor Airlines
• Contour Aviation
• Copa Airlines
• Delta Air Lines
• Eastern Airlines
• Edelweiss Air
• Elite Airways
• Etihad Airways
• Frontier Airlines
• Hawaiian Airlines
• InterCaribbean Airways
• Japan Airlines
• JetBlue Airways
• Key Lime Air
• KLM Royal Dutch Airlines
• Miami Air International
• Norwegian Air
• PAL Express
• Philippine Airlines
• Porter Airlines
• Qatar Airways
• Scandinavian Airlines
• Seaborne Airlines
• Silver Airways
• Singapore Airlines
• Southern Airways Express
• Southwest Airlines
• Spirit Airlines
• Sun Country Airlines
• Sunwing Airlines
• Swiss International Air Lines
• TAP Air Portugal
• Turkish Airlines
• United Airlines
• Virgin Atlantic
• VivaAerobus
• World Atlantic
• Xtra Airways

If you obtained your KTN through the Global Entry program or by virtue of your status as a US Armed Forces member, you should use it whenever you make an airline reservation, regardless of which airline you fly.

Why Don't I Get PreCheck Status Every Time?

There are several reasons why you might not be able to use the PreCheck screening lane, even though you have a KTN. For example:

Sometimes the TSA does not give PreCheck status to enrolled travelers as part of its effort to randomize security screening procedures.

The data you entered when you bought your ticket might not match the data on file with the TSA, DHS, or DoD. Your first name, middle name, last name, and date of birth must match exactly.

You may have entered your KTN incorrectly when you bought your ticket.

Your KTN might not be saved in your frequent flyer profile, or you may not have logged in to your frequent flyer account before you bought your ticket online.

If you bought your ticket through a travel agent or third party website, such as Expedia, your KTN might not have been passed along to your airline. The best way to correct this problem is to call your airline and make sure your KTN has been entered into your reservation record. Do this before you check-in for your flight.

You may not have noticed that you could not enter your KTN when you purchased your ticket online. This occasionally happens with online travel websites (third party websites). 

How to Resolve Problems

Once you have a KTN, you are supposed to use it. Always look for the KTN field when you buy an airline ticket online. Contact your airline after you complete your purchase if you do not see it.

Double-check your travel documents (driver's license, government-issued photo ID and/or passport ) to be sure your full name and birth date match the information you provided to the TSA or DHS. Save your KTN in your frequent flyer account record(s). Check your frequent flyer account profiles regularly to make sure your KTN is still entered correctly. Train yourself to look for the KTN field and enter your KTN whenever you buy an airline ticket. Call your airline before your check-in date to be sure your KTN has been added to your reservation record.

When you print your airline ticket, you should see the letters "TSA PRE" in the top left corner. These letters indicate that you have been selected for PreCheck status on your flight. If you are enrolled in PreCheck but do not see "TSA PRE" on your ticket, call your airline. The reservations agent will be able to help you sort out any problems. Remember that the TSA will not always select you for PreCheck status, even if you are enrolled in the PreCheck program.

If you encounter problems at check-in or at the airport, contact the TSA as soon as possible to find out what happened. According to the Wall Street Journal , the TSA only retains PreCheck data for three days after your flight, so you will need to act quickly.

What is a redress number for flying?

Do i need a redress number, how do i apply for a redress number, how do i use a redress number, redress numbers for tsa recapped.

Whenever you travel by air within, to or from the U.S., you’re electronically screened using the Transportation Security Administration Secure Flight screening program. While this system is transparent for most passengers, it occasionally misidentifies passengers as high risk.

If you've frequently been stopped for additional security during travel or have been denied travel for security reasons, you may consider applying for a redress number to avoid this in the future.

The redress number meaning is a numeric identifier given to individuals who were falsely identified as posing threats to transportation security or public safety when flying. It aims to streamline TSA checkpoints for these travelers.

Here's how redress numbers for travel work and if applying for one is a smart move for you.

The short answer is a redress number is an identifier that allows TSA to match you with the results of your redress case. A redress number is used by the TSA’s Secure Flight program to simplify the watchlist matching process and can prevent future false matches of people who have been misidentified as matching a watchlist in the past.

A redress number is different from a Known Traveler Number , which identifies your membership in Trusted Traveler programs like TSA PreCheck and Global Entry .

Most travelers won't have a redress number. Only people who have applied for the Department of Homeland Security’s Traveler Redress Inquiry Program, or TRIP, will have one.

If you don't have a redress number and an airline or travel site requests a redress number as part of a booking process, you'll simply leave that field blank.

If you've been denied travel or delayed during travel for additional security screening, or if you've had trouble getting through checkpoints at U.S. borders, DHS TRIP may provide relief from security-related travel woes.

Specifically, TSA suggests that you apply for a redress number if you've had issues like being unable to print a boarding pass, being denied or delayed boarding of a plane, being denied or delayed entry into or exit from the U.S. at a border checkpoint, or are frequently referred for additional screening at an airport.

Here is the list of issues that DHS says TRIP can help resolve:

You were unable to print a boarding pass from an airline ticketing kiosk or from the Internet.

You were delayed or denied boarding an aircraft.

The airline ticket agent informed you that the federal government was not authorizing you to travel.

You are repeatedly referred for secondary screening when clearing a U.S. Customs and Border Protection checkpoint or were denied entry into the U.S.

You were told by CBP at a U.S. port of entry that your fingerprints need to be corrected.

You wish to amend a traveler record because of an overstay as a result of not submitting the required I-94 when exiting the U.S.

You believe you were incorrectly denied ESTA authorization.

If you frequently experience issues like these when traveling, you might want to apply for DHS TRIP.

Note that TRIP is meant to resolve security-related issues like watchlist mismatches. It isn't intended to resolve customer-service complaints, address issues related to discrimination, help you find lost or damaged items or provide assistance during security screening.

Further, having a redress number doesn't guarantee that you'll never be selected for additional screening, but it makes additional screening less likely if you've been previously falsely matched to a watchlist.

You can apply for a redress number through the Traveler Redress Inquiry Program portal if you believe that you're being incorrectly stopped or screened when flying.

During the application process, you'll be asked a series of screening questions to determine if obtaining a redress number may help solve your travel issues.

To apply, you'll be required to submit ID documents proving your identity. U.S. citizens should provide a copy of the biographical page of an unexpired U.S. passport or, for those without one, a copy of an unexpired government-issued photo identification.

Minors may provide a copy of a birth certificate. Get more advice on how to successfully navigate TSA PreCheck with a family .

Non-U.S. citizens must provide a copy of the biographical page of an unexpired passport and/or copies of one of several U.S. government-issued identification documents. Acceptable identification documents include:

Passport card.

Driver's license.

Birth certificate (for people younger than 18.)

Military identification card.

Government identification card.

Certificate of citizenship.

Naturalization certificate.

Immigrant/non-immigrant visa.

Alien registration.

Petition or claim receipt.

I-94 admission form.

SENTRI card .

NEXUS card .

Border crossing card.

SEVIS card.

After the DHS receives and processes your application, it will send you a resolution letter detailing the outcome of your application. If you feel that your redress request was resolved incorrectly, you should follow the instructions in your resolution letter.

Making sure your redress number is attached to your air travel reservations will give you the greatest chance of avoiding security hassles when flying or crossing U.S. borders.

You can attach your redress number to a travel reservation during booking, you can add it to your frequent flyer profile or you can ask an airport agent to add your redress number to your reservation at check-in.

Enter your redress number during booking

Enter your redress number during the booking process when using most online travel agencies, airline websites or travel agents.

For example, when booking a flight on Expedia , you can enter your redress number after you provide your name, gender and date of birth. Look for the option to expand the “Frequent flyer, redress and more” section of this page.

Other online travel agencies and airline websites will typically have a similar option during their booking process.

Enter your redress number in your frequent flyer profile

If you belong to a frequent flyer program , you can add your redress number to your loyalty member profile. For many travelers, this is the most convenient way to ensure that your redress number is applied automatically to all their reservations. The process will vary by airline, but this can typically be done online, similarly to how you would add a known traveler number.

If you are a Delta Air Lines SkyMiles member, for example, you can add your redress number to the Secure Flight Info section of your profile. On Delta.com, your Secure Flight Information can be found under the Passenger Details section of your profile.

Similarly, Southwest Airlines members can enter their redress number under the “Travel related info” panel in the personal information section of their profile.

Exactly how to enter your information varies by airline, but the field to enter your redress number can typically be found in the same place where you enter your known traveler information.

Give your redress number to an airport agent

There may be times when you are unable to add your redress number to your reservation until check-in.

For example, if you book travel as part of a group tour package and your tour provider doesn’t provide your airline confirmation number, or if you booked through an online travel agency and forgot to add your redress number to your reservation, you may show up at the airport without your redress number attached to your reservation.

Most airport ticketing agents should be able to add your redress number to your reservation upon check-in.

While a redress number isn't required for travel and not everyone will need one, if you’ve experienced security-related issues while flying, applying for a redress number may be right for you. By adding it to your travel bookings or frequent flyer accounts, you can help TSA identify you to save time and stress.

How Do I Add My Known Traveler Number To An Existing Reservation

Published: November 9, 2023

Modified: December 28, 2023

by Shari Wyrick

• Travel Guide

Introduction

Adding your Known Traveler Number (KTN) to an existing reservation can save you time and hassle at the airport. If you’re a frequent traveler and have enrolled in a trusted traveler program like TSA PreCheck or Global Entry, you’ll want to make sure your KTN is associated with your flight reservation.

Having a KTN allows you to enjoy expedited security screening, skip the long lines, and keep your shoes and belt on. It’s a convenient perk that can make your travel experience smoother and more enjoyable. But what if you’ve already booked your flight and didn’t enter your KTN during the reservation process?

Don’t worry; adding your KTN to an existing reservation is relatively simple. Most airlines and online travel agencies provide an option to edit your reservation details, including adding your KTN. In this article, we’ll guide you through the step-by-step process of adding your Known Traveler Number to an existing reservation, ensuring a seamless travel experience.

Step 1: Accessing Your Existing Reservation

The first step in adding your Known Traveler Number to an existing reservation is to access your reservation details. This can be done through the airline’s website, mobile app, or by contacting their customer service.

If you booked your flight through an online travel agency such as Expedia or Kayak, you’ll need to log in to your account and navigate to the “Manage My Booking” or a similar section. Look for the option to view or modify your reservation.

When accessing your reservation, be sure to have your confirmation number or booking reference handy. This information is usually included in the confirmation email you received after making your booking. It helps the system retrieve your reservation quickly.

If you’re using the airline’s website or mobile app, you may also need to provide your last name to locate your booking. Enter the required details accurately to ensure a smooth access to your reservation.

Once you’ve successfully accessed your existing reservation, you’re ready to move on to the next step.

Step 2: Locating the “Known Traveler Number” Field

After accessing your existing reservation, the next step is to locate the “Known Traveler Number” field. This is where you will enter your KTN to associate it with your flight.

The location of this field may vary depending on the airline or travel agency’s website or app interface. Commonly, you can find it under the “Passenger Information” or “Traveler Details” section. Look for a subsection specifically related to security or trusted traveler programs.

If you’re having trouble finding the field, use the search function on the website or app for keywords like “Known Traveler Number” or “TSA PreCheck” to narrow down the options quickly.

In some cases, the airline or travel agency may have a dedicated section or form specifically for entering your KTN. This is especially true for those who have enrolled in trusted traveler programs like TSA PreCheck or Global Entry.

Once you’ve located the “Known Traveler Number” field, you’re ready to proceed to the next step and add your KTN to your reservation.

Step 3: Adding your Known Traveler Number

Now that you’ve located the “Known Traveler Number” field, it’s time to add your KTN to your existing reservation. Follow these steps to ensure a seamless process:

• First, double-check that you have your KTN handy. It is a nine-digit alphanumeric code that was provided to you when you enrolled in a trusted traveler program like TSA PreCheck or Global Entry. You may find it printed on your membership card, known traveler document, or through the secure login portal of the program you enrolled in.
• Enter your KTN accurately into the designated field. Be sure to double-check the information you entered to avoid any errors.
• If you are adding KTN for multiple passengers on the same reservation, ensure that you enter each person’s KTN separately in their respective fields, if available.
• Some airlines or travel agencies may also provide an option to select your trusted traveler program from a drop-down menu. Choose the correct program associated with your KTN if prompted.
• If you’re having trouble locating or adding your KTN, don’t hesitate to reach out to the airline’s customer service for assistance. They will be able to guide you through the process and ensure your KTN is successfully added to your reservation.

Remember, accurate entry of your KTN is crucial for a smooth travel experience. So take your time and double-check the information before moving on to the next step.

Step 4: Saving the Changes

After adding your Known Traveler Number (KTN) to your existing reservation, the final step is to save the changes you made. This ensures that your KTN is successfully associated with your flight and will be reflected in your travel documents.

Here’s what you need to do to save the changes:

What is a redress number and a known traveller number?

I went to fill out my information on the SAS website, and besides the usual, there were spaces for redress number and known traveller number. I just left it blank.

The redress number is provided to travelers who have a name that also appears on the Do Not Fly or "special screening" list when that traveler has filed a complaint with the TSA that they shouldn't be on those lists and have a like or similar name as another person.

Right now there isn't a known (trusted) traveler program on a Federal national or international level, but it's something that has been discussed. The Fly Clear program is the closest thing offered, but that number means nothing to the airline at this point. The space is there for future use.

You did the right thing by leaving it blank.

Redress number vs. known traveler number: understanding the difference.

In the world of customs and border protection, you may find some of the terminology unclear. For example, you may have heard of redress numbers vs. Known Traveler Numbers (KTN) in the context of airport security. But what do those terms mean and what are the differences?

What is a redress number?

Much like other travel identification numbers assigned by the government, a redress number is designed to expedite the border security process.

Redress numbers are issued by the Department of Homeland Security to individuals who have previously experienced difficulties during screening at transportation hubs such as airports. These difficulties may include watch list issues, screening problems at ports of entry and situations where a traveler believes they have been unfairly or incorrectly delayed, identified for additional screening or denied boarding.

If you do think you're eligible for a redress number, you can apply online through the Department of Homeland Security's website. After submitting your application, it will become subject to approval, which can take up to 50 business days.

Upon approval, you will receive your redress number, which you'll be able to use when traveling. This should help you avoid difficulties at security screenings going forward.

Note that if your security issues relate to a criminal record or an instance of excessive intoxication, you will likely not be eligible for a redress number.

What is a Known Traveler Number?

Separate from a redress number, a Known Traveler Number is issued to people who apply to and are approved for TSA PreCheck ® , the program that allows approved travelers to access expedited security lines for domestic travel in the United States.

Additionally, while the terminology is slightly different, a similar identification number is issued to those who apply to and are approved for Global Entry, NEXUS and SENTRI, programs that allow for expedited access into the United States via air, land or sea. In this case, you'll be issued a PASSID number, which is entered in the same place as the Known Traveler Number when booking air travel.

Like a redress number, a Known Traveler Number is also issued by the Department of Homeland Security, and recipients must go through an application and screening process to be approved. This then grants entry to the TSA PreCheck line, which allows travelers to go through airport security without removing liquids, laptops, shoes, belts or light outerwear.

Redress number vs. KTN: Differences and benefits

The main differences between a redress number and a Known Traveler Number are the circumstances in which it's issued and used.

A redress number relieves part of the stress of traveling by making it less likely you will be targeted for additional screening, or delayed or denied boarding or entry. Ultimately, the goal of a redress number is to create a smoother traveling experience for those who have had difficulties with security in the past. It works to correct the potential misidentification of travelers as high risk, thus complicating their experience through security.

By contrast, a Known Traveler Number allows travelers to access specially approved security lines and screening processes designed to expedite their wait time. Additionally, unless you are an active member of the military, you pay for this perk. TSA PreCheck costs $78 as of April 2023 for a five-year membership. This fee is subject to change, so be sure to check the TSA PreCheck website for the most up-to-date cost. A redress number, on the other hand, is free.

If comparing a redress number vs. a Known Traveler Number, you'll find the “why" behind the two numbers the biggest difference. Redress numbers are intended to correct misidentifications that may lead to security issues for certain travelers, while a Known Traveler Number is a travel perk you can pay for. Ultimately, their goal is the same — to help make your travel a little bit smoother.
