Can you bring a guest through TSA PreCheck? Usually, no, but there are exceptions. These include allowances for the following types of guests who don't have their own TSA PreCheck membership: spouses, children, those with a disability, and active military personnel.

Generally, travelers cannot use the dedicated TSA PreCheck lane unless they are enrolled in the program and have the indicator on their boarding pass. In 2026, the TSA has further tightened these rules to preserve the speed and integrity of the "Trusted Traveler" experience. However, children aged 12 and under can still accompany a parent or guardian who has PreCheck through the lane. For those aged 13 to 17, they can only join if they are on the same reservation and the PreCheck indicator also appears on their own boarding pass. It is important to note that even for members, access is not guaranteed; the TSA reserves the right to perform random security screenings. Furthermore, as of February 2026, some travelers have experienced minor disruptions due to federal funding lapses affecting the Department of Homeland Security, though TSA PreCheck remains operational as an "essential" service. Fumbling with documents is also being phased out for members at major airports through the expansion of Touchless ID, which uses facial recognition instead of physical IDs.
