I haven't seen it mentioned but the first thing I would do with QR reservations made with AAdvantage miles is to check the QR reservation directly. I always asked for the QR reservation # in the past but AA is helpful now in adding it to your AA reservation. I watch this directly most of the time after booking because it is the first place to see schedule changes
If you look at QR directly, it will have your baggage allowance - then you know everything that QR sees. Baggage allowance, booking code, etc
