Add TSA PreCheck to Expedia Flight After Booking

Adding TSA PreCheck to an already-booked Expedia flight is usually a quick process that saves you time at airport security. This guide explains how to update your Known Traveler Number (KTN) on an existing reservation, what to do if the option isn’t available, and how to avoid common pitfalls. You’ll need your TSA PreCheck KTN (a 9-digit number) and your Expedia itinerary number.

What You’ll Need

  • Your TSA PreCheck Known Traveler Number (KTN) – a 9-digit number on your approval letter or membership card.
  • Your Expedia itinerary number (found in your confirmation email or in the “My Trips” section of your Expedia account).
  • Access to the email address used for the booking, in case you need to contact Expedia or the airline.

Step-by-Step

  1. Log in to your Expedia account. Go to Expedia.com and sign in with the email and password you used to make the booking. If you booked as a guest, you can still access your trip via the “Manage Trip” option using your itinerary number and last name.
  2. Navigate to “My Trips.” Click on “My Trips” in the top right corner of the Expedia homepage. You’ll see a list of your upcoming trips. Find the flight you want to update and click on it.
  3. Click “Manage Trip” or “Change Flight.” On the trip details page, look for buttons like “Manage Trip,” “Change Flight,” or “Edit Details.” The exact wording varies, but it’s usually near the flight details. Click it to open the editing options.
  4. Look for the passenger details section. In the editing view, you’ll see a list of passengers on the reservation. Click on the passenger whose KTN you want to add. There should be a field labeled “Known Traveler Number,” “TSA PreCheck,” “KTN,” or “Redress Number.”
  5. Enter your 9-digit KTN. Type your KTN exactly as it appears on your TSA PreCheck approval. Double-check for typos – a single wrong digit will prevent the PreCheck indicator from appearing on your boarding pass.
  6. Save your changes. After entering the KTN, click “Save,” “Continue,” or “Update.” Expedia will typically send a confirmation email that the change was made.
  7. Check your boarding pass. The TSA PreCheck indicator (usually “TSA Pre✓™” or “TSA PRE”) will only appear on your boarding pass once the airline processes the KTN. This usually happens within 24-48 hours, but it can be immediate. Check your boarding pass online or in the airline’s app before you head to the airport. If it’s not there, contact the airline directly.

Common Mistakes

  • Entering the wrong KTN. A single digit error will invalidate your PreCheck status. Always copy the number from your official TSA document, not from memory.
  • Assuming PreCheck applies to all passengers. Each passenger on the reservation needs their own KTN. If you’re traveling with family, each person must have their own TSA PreCheck membership and their KTN must be added individually.
  • Waiting until the last minute. Airlines need time to process the KTN. If you add it within 24 hours of departure, it may not appear on your boarding pass, and you’ll have to go through the regular security line.
  • Using the wrong field. Some airlines have separate fields for “Redress Number” (for travelers with a DHS redress number) and “Known Traveler Number.” Make sure you’re putting the KTN in the correct field.
  • Not checking your boarding pass. Even after adding the KTN, you must verify that the PreCheck indicator appears on your boarding pass. If it doesn’t, you’ll be sent to the standard line.

Tips

  • Add your KTN to your frequent flyer profile. If you have a frequent flyer account with the airline you’re flying, add your KTN there. This way, it will automatically be applied to future bookings, even if you book through Expedia.
  • Use the airline’s website or app. If Expedia’s interface doesn’t show the KTN field, go directly to the airline’s website, find your reservation using the airline confirmation code (which is different from the Expedia itinerary number), and add the KTN there.
  • Call Expedia or the airline if you’re stuck. If you can’t find the field or the system won’t let you save, call Expedia customer service or the airline directly. They can manually add the KTN to your reservation.
  • Add your KTN when booking. For future bookings, always enter your KTN during the passenger information step. This saves you the hassle of updating later.

Troubleshooting

I can’t find the KTN field in Expedia. Some bookings, especially those made through third-party partners or with certain airlines, may not display the KTN field. In this case, use the airline’s website or app. You’ll need your airline confirmation number, which is listed in your Expedia itinerary. Log in to the airline’s site, find “Manage Booking,” and add your KTN there.

I added my KTN but the PreCheck indicator isn’t on my boarding pass. First, check that you entered the number correctly. If it’s correct, wait up to 48 hours. If it’s still not showing, contact the airline directly. They can verify if the KTN was received and process it manually.

Expedia says my change was saved, but the airline doesn’t show it. This can happen if there’s a delay in syncing between Expedia and the airline. Wait a few hours and check again. If it persists, call the airline – they have the final say on your reservation.

My flight is in less than 24 hours and I just added the KTN. The airline may not process it in time. You can still try to add it via the airline’s app, and if it doesn’t appear, you’ll have to go through standard security. Note that TSA PreCheck is not guaranteed – it’s at the discretion of the TSA and the airline.

Frequently Asked Questions

Does adding TSA PreCheck to an Expedia booking cost anything? No, adding your KTN to an existing reservation is free. You only pay for the TSA PreCheck membership itself (which is valid for 5 years).

Can I add TSA PreCheck to a flight booked with points or miles? Yes, as long as the reservation is in your name and you have a KTN, you can add it regardless of how you paid.

Will TSA PreCheck apply to all my flights on the same itinerary? If all flights are on the same reservation and operated by airlines that participate in TSA PreCheck, yes. However, if you have separate bookings for connecting flights, you may need to add the KTN to each booking.

What if I don’t have TSA PreCheck yet? You can apply online at the TSA website and schedule an in-person interview. Once approved, you’ll receive a KTN. You can add it to your Expedia booking as soon as you have it.

Can I add TSA PreCheck for a child? Children under 12 can accompany a TSA PreCheck parent or guardian through the PreCheck lane without their own membership. However, if a child is traveling alone, they need their own membership. You can add a child’s KTN the same way you would for an adult.

What if my KTN is not recognized by the airline? Double-check the number and try again. If it still fails, contact TSA PreCheck customer service to verify your KTN is active. It’s also possible the airline doesn’t participate in TSA PreCheck – check the airline’s list of participating carriers.
