What is TSA PreCheck®?

TSA PreCheck®, like Global Entry, NEXUS and SENTRI, is a Trusted Traveler Program offered by the Transportation Security Administration (TSA) that can help you move through airport security faster. 
Becoming a TSA PreCheck® member requires an application, in-person appointment and enrollment fee. Upon approval, you get a Known Traveler Number (KTN). By adding the KTN to your flight reservations, you can enjoy shorter security lines and an easier screening process at over 200 airports and 90 airlines.

Can you add TSA PreCheck® after booking?

If you didn’t include your TSA PreCheck® number when booking a flight, it’s possible to add it later. You might be able to add it to a reservation through the airline’s mobile app or contact the airline online or by phone.

Can you add your KTN to an existing reservation?

TSA issues each TSA PreCheck® member a KTN that grants access to expedited security lines. So adding a KTN to an existing reservation is the same as adding TSA PreCheck® after booking.

How to add TSA PreCheck® to an existing reservation

Airlines may differ, but it’s often possible to add TSA PreCheck® once you’ve already booked a flight.

American 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.

Delta Air Lines

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

Frontier Airlines

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

Southwest Airlines

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.

Spirit Airlines

Find an upcoming trip with Spirit to add a KTN.

United Airlines

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

What if TSA PreCheck® isn’t on your boarding pass?

It’s a good idea to add your KTN when booking a flight so that it shows up on your boarding pass. But if you forgot to add your KTN or it’s not shown on your boarding pass, there are a few things you can do.
You can contact the airline to add your KTN after booking or to make sure you entered your name, date of birth and KTN correctly. If your KTN still doesn’t show up, consider checking that your TSA PreCheck® membership is active. You can also submit an online form or call the TSA at (866) 289-9673.

If your spouse isn’t also enrolled in TSA PreCheck®, they aren’t cleared to accompany you through the expedited security lane.
