According to current TSA regulations in 2026, you can still use a government-issued ID (such as a driver's license or passport) for domestic travel up to two years after its expiration date. This policy is intended to help travelers who may have experienced delays in the renewal process. However, this only applies to domestic flights within the United States. For international travel, you must have a valid, unexpired passport, and many countries require it to be valid for at least six months beyond your departure date. If your ID is more than two years expired, or if you have no ID at all, you may still be allowed to fly if you arrive at the airport early and complete an identity verification process (TSA ConfirmID), which involves an administrative fee and providing alternative documents like credit cards or utility bills.
