Wondering How Do You Add TSA PreCheck® to Southwest Airlines? It’s easy! Start by logging into your Rapid Rewards® account and entering your Known Traveler Number (KTN) under your profile. This ensures TSA PreCheck® is automatically applied to future bookings. If you’ve already booked your flight, head to the “Manage Reservations” page on Southwest’s website and add your KTN there. Once added, TSA PreCheck® will show up on your boarding pass, letting you breeze through security without removing shoes, belts, or laptops. Adding TSA PreCheck® makes traveling with Southwest faster and more convenient.
