Ignoring the fact that the points you collect are worth so very little now, my complaint is now that you collect so few unless you travel business class.
I admit I have always used AF & KLM because they fly from a convenient local airport but will now just go for the flight that is most convenient and best value.
The rules have become amazingly complicated involving which flights count for what and which airlines are involved. I flew to Australia (return) with Malaysian Airlines who are supposed to be in the alliance but got no credit on Flying Blue whatsoever. I also realise that unless you book via the AF or KLM sites then you are almost certainly faced with making a retro claim for any credit. When the credits arrive they are worthless as the flight was of one particular class or another. With two almost identically priced flights with Vietnam Airlines, one received 50% of the miles and the other received nothing as it was the wrong class.
I know the whole airmiles system is really geared to those flying regularly in business or first class and probably do not pay for their own tickets. If I am going to face reality in the future then I hope AF & KLM do the same and don't promote Flying Blue as some amazing benefit.
