A recent development in AA's system: cannot issue baggage tags or BPs for QF flights, even though the flight segment is visible and correct in the PNR. Solution is to use the AA codeshare number instead -- but the correct QF flight number prints instead of AA. The poor Aagent went through 8 baggage tags before figuring this out on my last AA/QF interlined flight. QF got its revenge: my QF checked bag was first out, and the AA interlined bags were last out. Presumably a coincidence as they were identically tagged, but it seems interlined bags were put into a separate container on that flight.

So, if having trouble checking in at AA for a QF flight, tell the Aagent to use the AA codeshare number instead. AA no longer sells QF on aa.com, it is always the AA codeshare that appears (even if priced differently, and even when selecting "all airlines" -- which brings up DL and UA but not QF as alternatives, in this great Oneworld alliance). It looks like the AA codeshare rollout was a bit overzealous and has broken the baggage tag and boarding pass generation.
