I was relying on information provided by what I believed to be a reliable source. I thank you for the details and stand corrected.
As I said, I will concede to differentiating the number of miles according to fare basis. I think the non crediting of segments is too much. Whatever fare was paid to AF could have been paid to another company. In this case I chose AF between two close price offers, because I wished to keep my frequent flier status. My basic point remains that I no longer have this incentive in what, for airlines, is a highly competitive market, and I merely wonder at the logic.
However, if this is the worst that happens on my travels, I shall consider myself lucky.
