If OP is crediting to a star alliance partner (as seems to be hinted at in the post) then be aware that many of the star alliance programs credit ZERO for the ‘P’ booking class. I learned this the hard way when I was flying LX but crediting to TK where I have Star Gold. Had I known up front, I would have credited to my Miles and More account instead, just to get something, and used my TK card for the Senator Lounge or just slummed it in the Business Lounge but in either case, still gotten some miles.

I have to say I was pretty surprised that a good value but certainly not cheap business fare would earn nothing, when considerably cheaper economy fares still earned redeemable and status miles!
