In the event you arrive at the airport without proper ID, because it is lost or at home, you may still be allowed to fly. By providing additional information, TSA has other ways to confirm your identity, like using publicly available databases, so you can reach your flight.

Yes, you can still fly domestically within the United States if you have lost your ID, but you must undergo a more rigorous identity verification process. As of February 2026, the TSA has introduced a new option where travelers without a REAL ID or acceptable alternative can pay a $45 fee for "TSA ConfirmID," an electronic system that attempts to verify your identity using public databases. If you do not wish to pay or the system is unavailable, you should arrive at the airport at least two to three hours early to speak with a TSA officer. They will ask a series of questions based on your personal history (such as past addresses or vehicle records) to confirm you are who you say you are. You may also be asked to provide any other identifying items you do have, such as credit cards, a social security card, or even a prescription with your name on it. Once verified, you will be allowed through security, but you will likely be subject to enhanced screening, including a more thorough pat-down and luggage search. Note that this only applies to domestic flights; you cannot board an international flight without a valid passport.
