Hello, just booked a TK flight from Istanbul to Zurich with Aegean miles. The booking code was nog working on the TK website. Asked on twiiter to Aegean and they gave me another booking code for TK. Still nog working but other message on the TK website, something with the sales channel in which is was formed. Anyone of you had experience with that? Should I be worried about anything? How to change seats for the flight? At Istandbul checking in with TK or Aegean? Thanks in advance for your replies and feel free to move to other forum if necessary.
