Looking to maybe book this flight (on the American Airlines website) from London Heathrow to Miami. Just wanted to check that when it says "operated by BA" that it will be a BA plane and not an AA plane. I think this is the case as it says plane would be a 747-400 and AA don't have one (according to Seat Guru anyway) but BA do.
Am I correct with this. I don't really want to fly all that way on a single aisle plane and potentially no seat back IFE.
