You can still fly domestic flights without a REAL ID as of 2025, but you will be subject to additional screening by TSA at the airport. The deadline for mandatory REAL ID compliance was May 7, 2025. If passengers do not present a REAL ID-compliant ID, TSA has alternative methods to confirm identity, but this process may take longer, so arriving early is advised. Other acceptable IDs that can be used instead of a REAL ID include a valid U.S. passport or passport card, DHS trusted traveler cards, U.S. military ID, permanent resident card, and some state-issued enhanced driver's licenses. However, if you refuse to show any form of acceptable ID, TSA will not allow you through security.
In summary, flying domestic without a REAL ID is possible with alternative acceptable IDs or extra TSA screening, but a REAL ID or equivalent is strongly recommended to ensure a smooth process.
