No, absolutely NOT true, as I stated above, On KL it IS Y and S, on AF the same. On Delta it is Y B or M fares. I do not know what CO's rules are, but then again they are leaving Skyteam in the next 12 months anyway. Again, you may be right, but we don't know, although I should add that in Star alliance it is generally the top 2-3 fares on most member airlines and this program has been instituted in order to compete directly with Star Alliance.
