My wife and I were moved from 2A/C (front row of the 737) to 4D/E yesterday in Club as we boarded the plane. As compensation, we were given a couple of little bottles of champagne, and my wife was allowed to chose any fragrance she liked from the HighLife shop... nicely handled cabin crew!
(I've got quite long legs which press against the seat infront, even in Club Europe, which is why I always OLCI to get front row A/C)
