[QUOTE=graraps]
but the bad thing about AF's FFP is that you won't earn miles for some booking classes on partner airlines. These sometimes are excluded because they're cheap fares (KE Q-class), but other times it seems like somebody designated them just for fun- for example D on AM and AZ (business class with minimal restrictions). Thankfully these classes aren't too many. [QUOTE]

Are you saying that I do not earn FFP miles flying Z (discount business) on AZ, let alone business class miles?

That does not show up on their website(not much does show up on their website). Do they have similar restrictions for D & Z on AF?

AF, AZ, and NW frequently sell Z tickets IAD-Europe, which I use.
