How to add TSA PreCheck after booking a flight
If you have TSA PreCheck®, you can add your Known Traveler Number (KTN) when you book a flight. But if you forget to add it during booking, you can likely still update your boarding pass later on. But the process can vary by airline.
Typically, once you successfully add your TSA PreCheck information, the TSA PreCheck logo will appear on your boarding pass—getting you through airport security faster.
What you’ll learn:
-
TSA PreCheck helps members move more quickly and efficiently through airport security checkpoints.
-
If you don’t include your TSA PreCheck information when you book a flight, you may be able to add it later on.
-
When adding your TSA PreCheck information to an existing flight, you’ll need to make sure everything matches what you provided during enrollment.
-
Some Capital One travel cards offer cardholders a statement credit for the TSA PreCheck application fee.
How to get TSA PreCheck
Becoming a TSA PreCheck member requires an application, in-person appointment and enrollment fee. If you’re approved, you’ll get a KTN. You’ll need to add this number to your flight reservation for the TSA PreCheck logo to appear on your boarding pass. Then, you’ll have access to the TSA PreCheck lane.
You’ll typically receive your KTN within three to five days of completing the application process. In some cases, it can take up to 60 days. Your membership lasts for five years, and you can renew it up to six months before it expires.
Can you add TSA PreCheck after booking?
You can add your TSA PreCheck KTN after booking if you didn’t include it when purchasing the flight. The specific process may vary by airline, but here are some general steps to follow:
-
Find your trip on the airline’s website or mobile app.
-
Add your KTN to the passenger information section.
-
Save the changes.
-
Check your boarding pass to make sure the TSA PreCheck logo appears.
If adding your KTN through the app or website doesn’t work, you can try contacting the airline by phone.
What if the TSA PreCheck logo isn’t on your boarding pass?
If the TSA PreCheck logo doesn’t appear on your boarding pass after you’ve added your KTN to a reservation, you may want to check that your TSA PreCheck membership is active. You can also submit an online TSA form or call the TSA at 866-289-9673.
How to add TSA PreCheck after booking with specific airlines
Once you’re a TSA PreCheck member, you’ll share your KTN with the airline you’re flying with. Make sure the personal information you provide to the airline matches exactly what you used during TSA PreCheck enrollment.
Each airline may have a different process for you to provide your KTN. Here’s how to share your TSA PreCheck information with various airlines:
