I have an upcoming flight from KUL to IST on TK63 on business
When i selected my seat two weeks back, its a 787 seat map
However, looking at the recent flights and my flight itinerary on TK app, it seems like it is going to be operated by a 777.
However, the seat selections have been locked and not updated to a 777 config and i am unable to change my seats.
Is there anyway to change my seat selection if the aircraft has been swopped?
