What is a KTN and Why Do I Need It?
A Known Traveler Number (KTN) is issued to individuals who have been approved for a trusted traveler program like TSA PreCheck, Global Entry, NEXUS, or SENTRI. This number allows you to receive expedited security screening at participating airports, meaning shorter lines, and often, you don't need to remove your shoes, belts, light jackets, laptops, or 3-1-1 liquids from your bags. It's a game-changer for frequent flyers!
Step 2: Accessing Your American Airlines Reservation
There are a few ways to get to your booking on American Airlines. Choose the method that's most convenient for you.
Option A: Via the American Airlines Website (Recommended)
Go to AA.com: Open your web browser and navigate to
www.aa.com Log In (If Applicable): If you have an AAdvantage account and booked your flight while logged in, it's highly recommended to log in first. This makes the process smoother as your KTN can often be saved to your profile for future bookings.
Find Your Trip: On the homepage, look for a section like "Manage trips/Check-in" or "Your Trips." Click on it.
Enter Reservation Details: You'll be prompted to enter your first name, last name, and the confirmation number (also known as the Record Locator) for your reservation. This 6-character code is typically found in your booking confirmation email.
Retrieve Your Trip: Click "Find trip" or a similar button to pull up your reservation details.
Option B: Via the American Airlines Mobile App
Tip: Reread key phrases to strengthen memory.
Open the American Airlines App: Launch the official American Airlines app on your smartphone or tablet.
Log In (If Applicable): Similar to the website, log in to your AAdvantage account if you have one.
Navigate to "Trips": Look for a "Trips" or "My Trips" section within the app, usually at the bottom navigation bar.
Select Your Trip: Your upcoming trips should be listed. Tap on the specific trip you want to modify.
Option C: Booking Through a Third-Party Site (e.g., Expedia, Priceline)
If you booked your American Airlines flight through an online travel agency (OTA) like Expedia, Priceline, or a corporate travel portal, the process can sometimes be a little different.
Find Your AA Record Locator: Even if you booked through a third party, you should have received a confirmation email from them that includes the American Airlines record locator. This is crucial.
Proceed as per Option A or B: Use the American Airlines record locator to access your trip directly on AA.com or the American Airlines app, as described above. Many third-party sites don't allow KTN updates directly on their platform, so going to American Airlines' own channels is often necessary.
Step 3: Locating the Passenger Information Section
Once you've successfully accessed your reservation, you'll need to find the section where you can edit passenger details.
Look for "Edit Passenger Details" or "Security Information": Within your trip summary, you'll need to find a button or link that allows you to edit passenger information or security information. This might be under a general "Manage Trip" or "View Details" section.
Often, it's labeled something like "Edit Passenger Details," "Add/Edit Passenger Information," or "Security Information (optional)."
Hint: Sometimes this option is a small "pencil" icon next to your name or within a section labeled "Travelers" or "Passengers."
Click to Edit: Click on the appropriate link or button to open the passenger information editing screen.
Step 4: Adding Your KTN (The Core Step!)
This is where the magic happens!
Find the KTN Field: On the passenger information screen, look for a dedicated field labeled "Known Traveler Number" or "KTN." For Global Entry members, it might also be labeled "PASSID."
Enter Your KTN Exactly: This is critical. Type in your KTN exactly as it appears on your TSA/DHS profile. Even a small typo or a mismatch in your name (e.g., full middle name vs. middle initial, or missing a hyphen) can prevent TSA PreCheck from appearing on your boarding pass.
Double-check: It's worth taking an extra second here to ensure accuracy.
Add for Each Passenger (If Applicable): If you are traveling with others on the same reservation and they also have KTNs, you will need to add their individual KTNs to their respective passenger profiles within the booking. A KTN is personal and does not automatically apply to other travelers, even children over 12. Children 12 and under typically can accompany a KTN-holding parent through PreCheck without their own KTN.
Save Your Changes: After entering your KTN, be sure to click "Save Changes," "Update Information," or a similar button to confirm the addition.
Step 5: Verifying Your KTN and Boarding Pass
After saving your KTN, it's important to verify that it has been successfully applied to your reservation and will reflect on your boarding pass.
Sub-heading: Checking Your Reservation Online/In-App
Reminder: Revisit older posts — they stay useful.
Revisit Your Trip: Go back to your trip summary on AA.com or in the app.
Confirm KTN is Visible: You should now see your KTN listed within your passenger details.
Look for PreCheck Indicator: For many airlines, including American, if the KTN is successfully processed, you may see a "TSA PreCheck" indicator next to your name or within the security information section of your reservation.
Sub-heading: Getting Your Boarding Pass with PreCheck
 |
If you haven't checked in yet: When you check in for your flight (online, via the app, or at the airport kiosk), your boarding pass should automatically display the "TSA PreCheck" indicator.
If you have already checked in: This is a common scenario.
Update Boarding Pass: You will likely need to re-issue your boarding pass for the PreCheck indicator to appear. This often means going back to your trip on AA.com or the app, and selecting "Get Boarding Pass" or "Email Boarding Pass" again.
Airport Kiosk: If online re-issuing doesn't work or you prefer, you can often go to an American Airlines self-service kiosk at the airport and print a new boarding pass, which should now have the PreCheck indicator.
Airline Counter: If all else fails, a helpful agent at the American Airlines check-in counter can assist you in re-issuing your boarding pass with the KTN.
Step 6: What If PreCheck Still Doesn't Show Up?
Occasionally, despite following all steps, the TSA PreCheck indicator might not appear. Don't fret! There are a few common reasons and solutions:
Name Mismatch: The most frequent culprit! Ensure your name (first, middle, last) and date of birth in your American Airlines reservation exactly match what is on file with DHS/TSA for your KTN. Even minor discrepancies can cause issues.
Booking Too Close to Departure: While generally you can add a KTN last-minute, for optimal results, it's best to add it at least 72 hours before your flight.
System Glitch: Technology isn't always perfect.
Random Security Screening: Even with a KTN, TSA uses unpredictable security measures. You are never guaranteed expedited screening every single time.
Expired KTN: Double-check that your KTN is still active and hasn't expired. You can verify this on the DHS/TSA website.
Sub-heading: Reaching Out for Assistance
If you've checked everything and your PreCheck still isn't showing, it's time to contact American Airlines directly.
Call American Airlines Reservations: This is often the quickest and most effective method. Have your record locator and KTN ready. The agents can often manually add or verify your KTN. You can find their contact number on AA.com under "Contact Us."
Use the American Airlines Chat Feature: Many airlines offer a chat function within their app or on their website. This can be a convenient way to get assistance.
Ask at the Airport: As a last resort, if you're at the airport, speak to an American Airlines agent at the check-in counter. They can usually resolve KTN issues on the spot and print a new boarding pass.
