How to Add TSA PreCheck to Your American Airlines Reservation

Learn how to add TSA PreCheck to your American Airlines reservation. Follow these steps and ensure your KTN is added before printing your boarding pass.

To add TSA PreCheck to your American Airlines reservation, follow these steps:

  1. Log in to your AAdvantage account on the American Airlines website or app[1].
  2. From “Your account”, choose “Information and password”[1].
  3. In the “Secure traveler” section, add your PASS ID or Known Traveler Number (KTN) in the “Known Traveler Number” field[1].

By adding your KTN to your AAdvantage profile, it will be automatically applied to your future reservations when you book through your account or when you attach your loyalty number to a reservation[2].

If you’re not logged in to your AAdvantage account or don’t have one, you can still add your TSA PreCheck number during the booking process. After selecting your flight date and time, enter your passenger details. You can manually enter your PreCheck number under the passenger’s detail section[3].

To add TSA PreCheck to an existing reservation:

  1. Visit the American Airlines website and log in to your AAdvantage account[4].
  2. Access your reservation and select “Add/Edit Passenger Information”[4].
  3. Add your PreCheck or KTN number[4].

If you’ve already checked in and need to add your TSA PreCheck number to your boarding pass, you can visit the airline check-in counter at the airport and ask to add your PASS ID and KTN number to your itinerary[5]. Alternatively, you can try updating your reservation online by accessing the “Manage booking” section on the American Airlines website[6].

Remember that having TSA PreCheck on your boarding pass is necessary to use the expedited security lanes at the airport. Ensure your KTN is added to your reservation before printing your boarding pass[3].
