What if my passport does not have my preferred name/name I used to book a flight?
Passengers on an airplane must provide proof of identity when they check-in for their flight. Your name must match that on your passport or government-issued photographic ID. If you do have different names and genders or different documents however, you might be able to choose which one to use, provided it meets airline ID requirements and matches the name used on your reservation. You should check with your airline/travel agent before booking.
