Sorry, what are Y, F and J? You said 40,000 in Y, 60,000 in J and 80,000 in F.
Since, I wish to fly on Turkish or Ethihad and not Asiana, how many miles do I need for Seoul to Athens and Zurich/Milan to Seoul?
Or London to Seoul? On Turkish or Ethihad or any others who fly to Athens, Zurich, London or Milan?
Thanks
