American does note that the amount of EQMs earned on partner airlines will change, I highlight «will» because the current link still reflect Elite Qualifying Points. (saverocity.com)
You also earn EQMs for flying on partner airlines, but the amount differs per partner. (upgradedpoints.com)
Under this system, if I book a cheap Business Class fare, I would earn more EQM per mile flown by booking though American Airlines but I would lose out on RDM. (travelingformiles.com)
