Mille Miglia (AZ) 100% on AF or KL in V-Class.
also on NW in V-class only 25%. But you get full files on all CO, DL, and AZ revenue booking classes. Upshot is, look at your travel pattern and select what is best for you.
If you want to compare FB and MM (AZ), you could also argue that FB gives you free domestic upgrades on NW and domestic lounge access; to my knowledge MM does not offer this!
