I'd assume meaning that some AA elites have gotten away with ticketing with minimal AA segments. That's a huge advantage (no pun intended) for AA members since we take a massive hit on LPs and RDMs earned on AA codes on a RTW.

I do recall one poster not too long ago with a base member getting away with using MIA-SCL as their AA coded flight to get AA tickets, which I would be ok with since the only AA operated codeshare I can find to anywhere in South America is the GRU flights from JFK and DFW (JL codes). So basically anywhere else in South America requires an AA code anyway, it's a necessary evil to go there to / from North America. In the past there were JL codes on GIG too, I flew on JL coded JFK-GIG-JFK in early 2020, but can't find it anymore. (*edit, it is still there, but JFK-GIG only operates in the North American winter season it appears, and JL doesn't put their code on MIA flights which makes sense but also oddly not the DFW-GIG flights which also reappear in winter, only JFK)
