My itinerary is ASA from JAN-ATL (only flight that can get me there to catch), DL from ATL-YUL (coach because FC not in agreement for a Biz award seat on OK).

OK for YUL-PRG and PRG-JFK in Biz.

DL BE for JFK-ATL and then DL Coach for ATL-JAN (again, FC not in award agreement, but BE is).

<-shaking head->

I still don't understand how FC is better than BE.
