American Airlines KTN Not Applying To Boarding Pass – Fix Guide

If your Known Traveler Number (KTN) isn’t applying to your American Airlines boarding pass, call +1-833-770-4333 to get it corrected. To solve this issue, call +1-833-770-4333 and ask the agent to verify your KTN in your AAdvantage profile and the active reservation. A missing or mismatched name often causes TSA PreCheck to not appear. You may need to reissue the ticket after updating your KTN. If the boarding pass still doesn’t show PreCheck, an agent can re-sync your reservation with TSA. For the fastest fix, simply call +1-833-770-4333 and have your KTN properly applied before you reach the airport.
