How to get TSA PreCheck

To apply for TSA PreCheck, you’ll pay a fee, submit personal information for a background check and attend an in-person interview. The application fee is $78, and membership is good for five years, which breaks down to $15.60 per year.

However, many travel credit cards reimburse the application fee simply for charging the application fee to that charge.

After the initial application fee to join the program, TSA PreCheck renewal — which is every five years to continue membership — costs $70 if completed online.

Each airline has its own process for adding TSA PreCheck to a ticket or to your frequent flyer profile. But no matter the airline, you’ll need your Known Traveler Number (KTN), which is the string of 9 or 10 digit-long numbers or letters unique to you if approved for TSA PreCheck. Note that adding your KTN to a ticket does not necessarily guarantee that it will be automatically applied to your next reservation.

That said, here’s a step-by-step guide to how to add TSA PreCheck to American Airlines, Delta Airlines, Southwest Airlines and United Airlines.
