Switching to Air France but using Delta points
I am Diamond on Delta (until 2012) and will be switching airlines to Air France based on a change of travel routine.
My question is this. Can I switch airline alliances, book and travel on AF but still use my delta miles ( I have a fair few) to upgrade for example? Or will these miles simply be only for booking on delta tickets......
Also, will AF status match my diamond medallion to their equivalent?
Thanks.
