Had the great opportunity to fly in an F seat last Tuesday from ZRH to ATH. Plane was fully booked and apparantly they needed all seats - I (United 1K - StarGold) was one of the lucky ones to expierence the F-Seat
As usual with these last minute operational upgrades this happened at the gate - asked at the lounge and it was not possible to get upgraded - but already saw that seats were occupied.
Great flight - compliments to the Swiss Crew
