TSA PreCheck does not work automatically for every flight, even if you're enrolled. After application and approval, your Known Traveler Number (KTN) must be added to your airline reservation to enjoy PreCheck benefits. Always check your boarding pass to ensure the TSA PreCheck indicator (such as “TSA PRE”) is present before heading to the airport.
