How does TSA PreCheck work?

TSA Pre✔® is a pre-screening initiative offered by the U.S. Transportation Security Administration (TSA) to help make your travel easier by saving you time and stress. This option is only available for our flights if you book on flyfrontier.com. Once you enroll, you will get a Known Traveler Number (KTN) that you will then add to your reservation so that the TSA Pre✔® logo appears on your boarding pass. This allows you to go directly to the TSA Pre✔® security line at participating airports.
