Understanding Your Known Traveler Number (KTN)
Before we dive into the "how-to," let's quickly clarify what a KTN is and where to find yours.
What is a KTN? Your Known Traveler Number (KTN) is a unique identifier assigned to you by the Transportation Security Administration (TSA) when you're approved for a Trusted Traveler Program like TSA PreCheck® or Global Entry. It tells the airlines and the TSA that you're eligible for expedited screening.
TSA PreCheck® KTN: If you enrolled directly in TSA PreCheck, your KTN is typically a 9 or 10-digit alphanumeric code that often starts with "TT," "TE," or "AC."
Global Entry/NEXUS/SENTRI KTN (PASSID): If you're a member of Global Entry, NEXUS, or SENTRI, your KTN is actually your 9-digit CBP PASSID. You can find this number on the back of your Global Entry, NEXUS, or SENTRI card in the upper-left corner, or by logging into your Trusted Traveler Programs (TTP) account online.
It's crucial that the KTN you enter matches exactly what the TSA has on file for you. Even a single digit or letter incorrect can prevent you from receiving PreCheck benefits.

| How To Add Known Traveler Number American Airlines |
Step 1: Locate Your American Airlines Booking or AAdvantage Account
There are two primary ways to add your KTN to American Airlines: either directly to a specific reservation or by updating your AAdvantage profile for future bookings. We'll cover both.
Option A: For an Existing Reservation
If you've already booked your flight, you'll need your six-character American Airlines confirmation code (also known as a Record Locator) and the last name of the primary passenger on the reservation.
Navigate to the American Airlines website (AA.com) and click on the "Manage trips/Check-in" tab on the homepage. Alternatively, open the American Airlines mobile app and go to "Your Trips."
Option B: For All Future Reservations (Recommended for AAdvantage Members)
If you're an AAdvantage member, adding your KTN to your profile is the most efficient method. Once updated, your KTN will automatically apply to all future bookings made while logged into your AAdvantage account.
You'll need your AAdvantage login credentials (username and password).
Head to AA.com and click "Sign In" in the top right corner.
Step 2: Adding Your KTN to an Existing Reservation
Tip: Pause, then continue with fresh focus.
If you have a flight already booked and need to add your KTN, follow these steps:
Sub-heading 2.1: Via American Airlines Website (AA.com)
Access Your Trip:
Go to AA.com.
Click on "Manage trips/Check-in" at the top of the page.
Enter your last name and the six-character confirmation code for your flight. Click "Find trip."
Navigate to Passenger Information:
Once your trip details load, look for a section labeled "Passenger information," "Edit passenger details," or similar. This is usually found within a "Passenger Summary" or "Security Information" tab.
Click the "Edit" button next to your name or the passenger you wish to update.
Enter Your KTN:
You should see a field specifically for "Known Traveler Number" or "PASSID."
Carefully enter your KTN (or PASSID if you're a Global Entry member) into this field.
Double-check for accuracy! This is paramount. Ensure the number is exactly as it appears on your official KTN notification or Global Entry card. Also, verify that your name and date of birth on the reservation precisely match what TSA has on file. Even a slight discrepancy can prevent PreCheck from being applied.
Save Your Changes:
Click "Save" or "Update" to apply the KTN to your reservation.
Verify PreCheck Status:
After saving, it may take a few minutes for the system to process.
Check your reservation details again. You should see a "TSA PreCheck" indicator on your boarding pass (once issued or reissued) or within your reservation details online.
Important Note: If you've already checked in for your flight before adding your KTN, you'll likely need to re-check in or regenerate your boarding pass to see the TSA PreCheck indicator.
Sub-heading 2.2: Via American Airlines Mobile App
Tip: Don’t just glance — focus.
Open the App and Find Your Trip:
Launch the American Airlines app on your smartphone.
Tap on "Your Trips" at the bottom of the screen.
Select the relevant upcoming trip.
Access Passenger Details:
Scroll down to the "Passenger details" or "Travelers" section.
Tap "Edit" or on your name.
Input KTN:
Find the "Known Traveler Number (KTN)" field.
Enter your KTN precisely.
Confirm and Save:
Tap "Done" or "Save" to finalize the update.
As with the website, you might need to refresh your boarding pass if you've already checked in.
Sub-heading 2.3: By Calling American Airlines Customer Service
 |
If you encounter any issues online or prefer speaking to a representative, you can always call American Airlines customer service.
Have your confirmation code and KTN ready.
Their phone number for U.S. and Canada is typically +1 (800) 433-7300. For international numbers, check the "Contact Us" section on AA.com.
Be prepared to provide your personal details for verification.
Step 3: Adding Your KTN to Your AAdvantage Profile (For All Future Bookings)
This is the best practice for AAdvantage members as it automates the KTN addition for all future American Airlines flights.
Tip: Check back if you skimmed too fast.
Log In to Your AAdvantage Account:
Go to AA.com.
Click "Sign In" in the top right corner and enter your AAdvantage number/username and password.
Access Your Profile:
Once logged in, hover over your name in the top right corner.
Click on "Account" or "Profile."
Navigate to Secure Traveler Information:
Look for a section like "Information and password," "Traveler Information," or specifically "Secure Traveler."
Click on the edit option for this section.
Enter Your KTN/PASSID:
Within the "Secure Traveler" section, you'll find a field for "Known Traveler Number" or "PASSID."
Enter your KTN with extreme care, ensuring it matches your official record.
Also, verify that your full name (first, middle, last) and date of birth in your AAdvantage profile precisely match the information on your TSA PreCheck or Global Entry application. Mismatches are the most common reason for PreCheck not appearing.
Save Your Profile:
Click "Save changes" or "Update profile" to store your KTN.
Confirmation:
You should receive a confirmation that your profile has been updated.
From now on, any new bookings made while logged into this AAdvantage account should automatically include your KTN and qualify you for TSA PreCheck (provided all other eligibility criteria are met).
Important Considerations & Troubleshooting
Exact Match is Key: I cannot stress this enough: The name, date of birth, and KTN on your American Airlines reservation must exactly match the information you provided during your TSA PreCheck or Global Entry enrollment. This includes middle names, hyphens, and suffixes. If you recently changed your name, ensure it's updated with the TSA first, then with American Airlines.
Timeliness: While you can add your KTN at any time, it's best to add it at least 72 hours before your flight. This gives the system ample time to process the information and update your boarding pass.
Children and PreCheck: Children aged 12 and under traveling with a parent or guardian who has TSA PreCheck on their boarding pass can generally use the PreCheck lane. Children over 12 generally need their own KTN to receive PreCheck benefits.
Third-Party Bookings: If you booked your American Airlines flight through a third-party website (e.g., Expedia, Priceline, a travel agent), you might need to contact them directly to add your KTN to the reservation, or use the "Manage Trip" option on AA.com with your confirmation code. Some third-party sites may not allow direct modification after booking.
No PreCheck on Boarding Pass? If you've added your KTN but the "TSA PreCheck" indicator isn't appearing on your boarding pass, first re-check your reservation and AAdvantage profile for any typos or mismatches. If everything looks correct, try re-checking in for your flight. If it still doesn't appear, contact American Airlines customer service or the TSA Contact Center for assistance.
KTN Expiration: Remember that TSA PreCheck and Global Entry memberships have an expiration date (typically 5 years). Make sure your KTN is current and renewed before you travel.
