Flew YVR - FRA two days ago (Sep 11). Did the auction at Seatboost. Was surprised starting bid was $750 CAD as I heard people talking about upgrades starting at around $450 in Seatboost for Condor. Turns out regular business seats were sold out, auction was for remaining Prime Business Seat(s) (first row with more space and bigger screens). Won the upgrade for $850 CAD and had an amazing flight on one of their Prime Seats.
