How to add TSA PreCheck after booking a flight

If you have TSA PreCheck®, a Trusted Traveler Program (TTP) offered through the Transportation Security Administration (TSA), you’ll add your membership information when you book a flight. The TSA Precheck indicator will appear on your boarding pass—getting you through airport security faster. 

If you don’t include your TSA PreCheck information when booking a flight, you may be able to update your boarding pass later on.

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 update your boarding pass 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.

Becoming a TSA PreCheck member requires an application, in-person appointment and enrollment fee. If you’re approved, you’ll get a Known Traveler Number (KTN). You’ll need to add this number to your flight reservation for the TSA PreCheck logo to appear on your boarding pass and for access to the TSA PreCheck lane.

You’ll typically receive your KTN in three to five days. 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.

If you don’t add your TSA Precheck number when booking a flight, you can add it later through the airline’s website or mobile app. You could also try contacting the airline by phone.

If your KTN doesn’t appear on your boarding pass after you’ve added it 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.

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 enrollment—this ensures the TSA PreCheck indicator shows up on your boarding pass.

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:

You can add your KTN to an American Airlines trip online or in the mobile app. You can also save your KTN to an AAdvantage® account so it’s automatically added to reservations.

If you booked a Delta flight without adding your KTN, you can log in to your Delta account and add it.

You can find trips you’ve already booked with Frontier by entering your last name and confirmation code online. From there, you can add a KTN.

Southwest lets you add a KTN to a flight you’ve already booked. You can save your KTN in your Rapid Rewards® account so it applies to future flights.

For existing reservations, you can add a KTN online using Find my trips. You can also add your KTN during online check-in.

You can add your KTN to an existing United trip and to your United MileagePlus® profile.
