Thanks Flythetail and Orlandodlplat. I didn't realize I could access AF with a Delta reservation number. Our first "partner" flight. AF website shows our seats as 2A & 2B confirmed. Also today is the first time I've gotten the AF seat map to come up on Delta. It has been showing can not assigned seat on this flight. This eases my mind, as I knew they had the dreaded "middle seat" in BE.
