Do you need birthday to book flight?

Secure Flight requires airlines to ask for the following information when a passenger makes a reservation: full name, date of birth, and gender.



Yes, providing a date of birth (DOB) is a mandatory requirement for booking nearly all commercial flights in 2026. This is driven by the "Secure Flight" program managed by agencies like the TSA in the United States and similar security protocols internationally. The DOB, along with your full legal name and gender, is used to cross-reference passenger manifests against "No Fly" lists and other security watchlists. Additionally, the DOB is essential for airlines to determine the correct fare category; for example, infants (under 2), children (2–11), and seniors (over 65) may qualify for different pricing or tax structures. If you are booking for someone else, you cannot finalize the reservation without this information, as the "TSA Secure Flight" data field is required by law to be transmitted to the airline's system before a ticket can be issued. Always ensure the DOB matches the passenger's passport or government-issued ID exactly to avoid issues at the security checkpoint.
