Under the name change policy, Turkish Airlines allows its passengers to change their last name if they get married or divorced before departure. As per the name change policy, passengers can not change their full name; they will need to cancel their ticket and rebook a new flight. At the time of the last name change, you will need to submit your marriage or divorce certificate and pay the name change fee.
