Depends on what class you are flying. If you are in Biz or 1st, then yes. If I remember right, you can do it in first with a 4 continent and in biz with a 5. You can't really do it at all in economy because of the limitations on what earns mileage. Assuming you are in the US Aadvantage system, QF only accrues 70% (book the codeshare for 100%) and CX doesnt accrue any.
Many people here, including me, have done the DXB turnaround.
