I've booked a flight with BA from London Heathrow to Tucson and back with a stopover in Dallas each way.
The outbound flight from London to Dallas is on an AA plane. I was hoping to request a seat for this before online check in opens as I'd prefer an aisle seat if possible.
I'm very unclear if/how to do this. When I try to do it via my booking on BA it redirects me to the AA website, where it looks like I can reserve a seat for £39 but there is also a message on the AA website saying you can't prebook seats if you've booked the flight with another airline.
So not sure whether to proceed or not as I don't want to pay £39 for the seat only to find out its not valid!
Anyone been in a similar situation?
thanks in advance!
