The number of eilte qualifying miles will be the 1000 actual miles for the trip plus whatever class of service bonus may be given (if traveling in a higher fare). That is to say, there are two things that are tracked: WorldPerks miles that can be spent on awards; and elite qualifying miles that are used to figure out status qualification/requalification.
How do you figure out (before buying) what the Air France flight fare inventory earning potential might be? I was just looking on Orbitz and the Air France flight to AMS was $ 125 cheaper than NWA.
