Does TSA PreCheck work for standby?

PreCheck is determined by the TSA on a per flight basis. Until you're confirmed on the flight there's nothing for TSA to verify, thus you can't get PreCheck when standing-by, unless you have a BP for another confirmed flight where you were given PreCheck.



In 2026, TSA PreCheck generally works for standby passengers, provided the status is printed on your standby boarding pass. When you are added to a standby list, the airline’s system usually retains your "Known Traveler Number" (KTN) from your original profile or booking. If your digital or printed standby document displays the TSA PreCheck indicator, you can use the expedited lanes as usual. However, there is a catch: if you are cleared for a seat at the very last minute at the gate, you have already passed through security. If you are trying to enter the security checkpoint with only a standby priority document and no confirmed seat, some airports may require additional verification. Most major U.S. carriers now ensure that standby "boarding passes" (which allow you through security but don't have a seat number) are fully compatible with PreCheck. It is always a good idea to double-check that your KTN is correctly attached to your frequent flyer profile to ensure the "checkmark" appears even on standby status.
