Beginning May 7, 2025, all travelers aged 18 and over will need to present a REAL ID-compliant driver's license or another acceptable form of identification to board domestic flights. A REAL ID is a state-issued ID that meets federal security standards, which include a gold star in the upper right corner of the card. If you don’t have a REAL ID, you can still use other forms of identification, such as a valid U.S. passport, passport card, or DHS trusted traveler cards (like Global Entry). It's important to check your ID now and, if needed, get it updated before the deadline. Children under 18 are not required to show identification.
