I wonder if those lists are 100% correct?
About 2 months ago I was flying GRU-CDG in C (booking class I - which is equivalent to, let's say, D on LH) and I had an overall good experience (which is surprising considering this is AF).
During our final approach the purser came and said "I see you have used your miles to take this flight..." And I just replied "I am afraid you are wrong...".
He was very embarassed, and even showed me the mainfest that stated that! Possibly, to make up for that, he went on to say that they appreciatted my business very much and asked me if I needed anything before our landing.
If AF had any kind of discrimination, I would have been screwed.
