Yes, but only if they obtain a "Gate Pass" or "Escort Pass" from the airline. Since 2001, security regulations have prohibited non-passengers from going past the TSA checkpoint without a valid boarding pass. However, airlines can issue a Gate Pass at the check-in counter for specific reasons: accompanying an unaccompanied minor, assisting a passenger with a disability, or helping an elderly traveler who needs assistance. In 2026, some U.S. airports (like Seattle-Tacoma, Orlando, and New Orleans) have introduced "Visitor Pass" programs, which allow a limited number of non-travelers to apply 24 hours in advance to enter the terminal for shopping, dining, or seeing off loved ones. These visitors must undergo the same TSA screening as passengers. Unless you are at one of these specific airports or have a documented need for assistance, your friends or family must generally say their goodbyes at the security entrance.
