Yes, but only if you have a "Gate Pass" or a specific "Guest Pass" issued by the airline or the airport. Generally, the "sterile" area behind security is reserved for ticketed passengers, but as of 2026, many major U.S. airports (including Seattle, Orlando, and San Francisco) have rolled out Airport Guest Pass programs. These allow non-travelers to apply in advance (at least 24 hours) to go through security to accompany a minor, assist an elderly parent, or simply enjoy the dining and shopping at the terminal. You must still pass through the standard TSA screening and provide a REAL ID-compliant identification (which is strictly enforced as of February 2026). If you are not in one of these pilot programs, you can still request a "Gate Pass" directly from an airline's check-in counter for specific reasons, such as assisting a traveler with a disability or a "Young Traveler" flying alone. Without one of these digital or physical passes, the TSA will not allow you past the initial document checker, regardless of your reason for wanting to enter.
