RTW / Round the World ticket - earning AAdvantage Miles

I've had both so far, but I avoid AA codes when at all possible to minimize the risk. in 2022 I had DFW-GRU and GRU-JFK on AA codes actually credit as distance. In 2024 I had DFW-SAL and SAL-DFW credit as revenue, that's a short enough flight that it didn't hurt too bad, but the earnings were 50% of what they would have been if distance calculation. In your case the disparity will be much more since QR has such a nice multiplier with AAdvantage, additionally I have a slightly higher multiplier on AA's revenue base as EXP, but perhaps you'll be EXP before your flight which does help a bit. My SAL flight didn't have any codeshares so there wasn't any choice but to use the AA codes.
