What happens if I buy a flight ticket and then change my name?

The general rule for travelling during a name change is that the name on your flight ticket must match the name on your passport. For this reason, travellers are encouraged to reserve flight tickets using the same name, gender and birth date that is present on their passport. If you make a flight reservation and then change the name on your passport or identification, you should contact the airline to request a change of name. The airline may ask for documentation as proof of the name change. Whether the passenger will be charged for this service is normally judged by the airline according passenger's individual case. Passengers flying during a name change should try to make the airline aware of the name change as early as possible.
