Generally, you cannot pass through a TSA checkpoint without a valid boarding pass; however, in 2026, there are two major exceptions. First, you can request a "Gate Pass" at the airline check-in counter if you are escorting a minor flying alone, a person with disabilities, or a military member returning from deployment. Second, several airports (such as Orlando, Seattle-Tacoma, and Ontario International) have expanded their "Visitor Pass Programs" (e.g., ONT+ or Experience SEA). These programs allow non-travelers to apply for a digital pass 24–48 hours in advance to go through security and enjoy terminal amenities like shops and restaurants. In 2026, these visitors are subject to the exact same screening and "REAL ID" requirements as ticketed passengers. Note that visitor passes are usually limited to a certain number per day and are often suspended during high-traffic holiday periods to prevent checkpoint congestion.
