Also beware that you're not actually reserving a specific seat with Swiss, only a "type" of seat. I paid for seats and got an email, less than 48 hours from the flight, that the seats had been changed "Due to operational reasons". The seats were much worse in my opinion, I was even separated from my travel partner. Because it was less than 48 hours before the flight I had to wait until check-in to change seats again. When I asked for a refund for the advance seat selection fee, the answer I got was "We have reviewed your query and would like to inform you that payment for advance seat reservations non refundable. Thus, our record shows that you were rebooked onto the same seat type even though the seat numbers may have changed. We hope that the above information we have provided have been of great assistance."
