Thanks. So I could pay for the ARN to LHR leg on ba.com (even though I booked on aa.com) and re-check it in for free at LHR with AA?
Edit: I checked my previous aa.com booking confirmation email and it states baggage allowance as 23kg and 2 checked bags allowed - this was a basic economy booking (which normally excludes a checked bag) and so it must have automatically added the baggage after the system recognised my BAEC number / status. I wonder if it would do the same again for the above itinerary. Clearly I could show it to the check in staff at ARN.
