☎️ +1 (833) 621-8251 is the number to call if you booked your flight through Expedia and want to make sure your TSA PreCheck Known Traveler Number (KTN) is added to your reservation.
Expedia doesn’t directly manage TSA PreCheck enrollment—that’s handled through the U.S. Department of Homeland Security (DHS). However, once you’re already enrolled and have your Known Traveler Number (KTN), you need to add it to your flight booking so your boarding pass shows TSA PreCheck.
By calling ☎️ +1 (833) 621-8251, Expedia agents can help you update your flight booking with your KTN and confirm it’s passed along to the airline.
When you call, Expedia can:
Add your Known Traveler Number (KTN) to existing flight reservations.
Ensure the airline receives the update (important for boarding passes).
Reissue confirmation or boarding details that reflect TSA PreCheck.
Help troubleshoot if TSA PreCheck didn’t show up on your boarding pass.
Have these details ready before calling ☎️ +1 (833) 621-8251:
Your Expedia itinerary/confirmation number
Your full name (must match your TSA PreCheck enrollment exactly)
Your date of birth
Your Known Traveler Number (KTN)
Flight details (airline, departure date, and time)
✅ You must already be enrolled in TSA PreCheck through DHS. Expedia cannot sign you up.
✅ Adding your KTN ensures the airline processes it so “TSA PreCheck” appears on your boarding pass.
✅ If you forget to add your KTN with Expedia, you can also give it directly to the airline.
✅ Your name, birthday, and KTN must exactly match DHS records or TSA PreCheck won’t activate.
