Not exactly a newbie, but have not been on AA in a long time and not a member of AAdvantage. But now I have an upcoming ORD-MAD flight on AA, booked through IB as a codeshare, with AS FF number. No checked luggage.

Although the AA app can be used with the AA PNR and it let me enter my passport number, I am guessing that this is not enough to get a bp on the app. What is the procedure to get a bp? Can I scan my passport at a machine, and if so are there specific international-checkin machines at ORD?

On the way back I will be transferring from IB/Air Nostrum to AA and will presumably be given a bp that I would have to trade in for an AA bp at the gate at MAD. Or will the app give me a bp that works to board? Note again, not an AAdvantage member; AS only.

Many thanks!
