I have just turned red and am booked in coach on CDG-PEK (June 1st in H, return June 6th in V). Can anyone comment on the likelihood (or strategies...) of an upgrade on those flights? I will be connecting from ZRH. If that does not happen, which are the best coach seats for a tall person in a 77W? Seatexpert and Seatguru do not show that aircraft for AF.
