I read the pahtma´s message stating:

FB sites do not list this kind of fare-class but the FB customer support reply was "yes 100% of miles". But as i can't find confirmation anywhere i'm little suspicious. I am FB Elite / Silver.

I have had the experience, that even though I called 3 or 4 times and talked with different people, they answer the wrong thing respect to classes or airlines you can fly on to continue in the program, etc. The employees of the call center usually now less than the members. Only when you ask: Are you sure? Could you check? do they realize that they just gave you wrong information.
