AA seating on a BA flight number
I can't find this covered anywhere else (does anyone else find the search facility on this forum completely useless?).
I have several flights on AA booked via BA and I can't reserve seating on them either via the BA or AA sites. Is there a way to do this or do I just take my luck on the day?
Also, can I check-in online for those AA flights via the BA site or the AA site?
