Generally, no, a person without a valid boarding pass cannot go through TSA security to reach the gates, but there are a few notable exceptions in 2026. The most common way for a non-traveler to pass security is with a "Gate Pass." Airlines may issue these to individuals assisting a minor, a passenger with a disability, or a military member returning from deployment. Additionally, several U.S. airports (such as MCO, MSY, and SEA) have introduced "Visitor Pass" programs that allow a limited number of non-flying guests to apply for security clearance 24 hours in advance to enjoy the terminal's shops and restaurants or say goodbye at the gate. If you don't have a specific pass, you will be stopped at the document checker. It is also worth noting that as of February 2026, the TSA has implemented the ConfirmID program, which allows travelers who lost their ID to pay a $45 fee for identity verification, but this still requires a valid flight reservation to proceed.
