Thank you for the replies. I went back and in fact was not able to see the "view seats" option on the AA codeshare - I must have been at the computer for too long

I am concerned now about seat selection for this IB flight. There will be 3 of us, me, my husband and teen daughter. It sounds like we might be relegated to whatever they have left that day - is that true? We are booked on the IB flight - not the codeshare - but they are FF tickets. Also, do I gain anything by joining IB's FF program? The last post gave me the impression that this may help with seating. If this flight could be that horrible - I am now reconsidering this routing. Thank you! Cheryl
