Thanks!
So for those not too great at this (like me) here's the basic steps to make it easiest:
1- sign up for Avis wizard #/ prefered (if older then 25)
2- in "travel pref" put in the flying blue awd for ivory f982700 (now its always in your profile)
3- when making reservation (through u.s. rate!! ) give them a)your Avis wizard number,
B) your flying blue card number - but they can only register it as a air France ff# (so just tell them it's that)
Good luck!
Ps: I have not actually confirmed any of this yet , and if anything is wrong please correct!
