Add your Known Traveler Number (KTN) when booking flights and save it to your airline profile. Boarding passes showing “TSA Pre✓®” will allow access to the TSA PreCheck® lane at airport security.
Tip: When booking your flight, make sure the name on your ticket matches the name on your TSA PreCheck® application and the ID documents used during enrollment. If you have multiple legal names across documents, use the set that matches the name you plan to travel under.
