I booked a DONE4 through the AA RTW desk, ex-OSL with first 2 segments on QR. After ticketing, the QR booking record (different PNR from AA) does not list a baggage allowance. However, MH, the operator of the 3rd segment (same PNR as QR), lists the proper baggage allowance for all segments. The QR customer service desk is adamant that I have no baggage allowance. Similar occurrences have been noted on the AA forum: AA Qatar Award buyer beware (ensure baggage allowance)

My question: is there in fact an implicit agreement for OW RTW tickets? The OW website lists the default baggage allowance. The AA RTW desk as well as the X (Twitter) account states that for these tickets there is absolutely an agreed baggage allowance, but QR has a reputation for going by what's in their record and no other criteria.
