The TSA PreCheck indicator is strategically placed on your boarding pass to ensure quick identification by security personnel, but its exact location can vary slightly depending on the airline and the format of the ticket. On a digital or mobile boarding pass, the "TSA Pre" or "TSA Pre✓" logo typically appears in the top-right or top-left corner, often positioned directly above or near the scannable QR code. On printed paper boarding passes, you will usually find the logo in the upper portion of the document, clearly visible near your name and flight details. It is important to note that the status must be printed on the pass itself; you cannot simply show your KTN (Known Traveler Number) or a membership card to use the expedited lane. If you have been approved for PreCheck but do not see the indicator on your ticket, it often means your KTN was not correctly attached to that specific reservation or that the airline does not participate in the program. In such cases, you must visit the check-in counter to have the number added and the pass reprinted before heading to the security checkpoint to ensure you can access the dedicated PreCheck lanes.
