With changes to the AAdvantage program that make it so much more like United MileagePlus and Delta SkyMiles, elite frequent flyers at American especially are re-considering their loyalty.
Some members will do better with the changes (higher spending; those flying 75,000 – 99,999 miles a year with average or better spend) and many will do worse (especially lifetime elites).
American thinks these changes are going to be good for revenue, but American has been performing better than United financially already and Delta doesn’t think its frequent flyer program changes are a driver of their revenue premium.
