I actually don't quite understand how this works but also I don't want to call TK hotline now as I know they are processing a lot of calls and my flight does not depart until May.
My booking is HKG/IST/HAM and the miles I used for the redemption has already expired in Dec 2019. However, I would like to postpone my travel now. May I know if I will be only to make a one-time free change or get a credit or what?
Thanks in advance!
