Please note that it is NOT possible to ticket your award over the phone. Once you have completed your reservation you will be given a confirmation number. To pay for the award you need to visit a physical ticket office, where you will pay the taxes and have your miles deducted in exchange for an e-ticket number. You can do this at any Turkish Airlines ticket office in the entire world.
How long is the reservation valid? Just wondering if I can make a booking over the phone, receive a PNR and ticket it and pay in the office in a couple of weeks. Is there any deadline?
