Amex Membership Rewards has 18+ international airline transfer partners — the deepest map in points travel. Citi ThankYou Points has fewer partners but uniquely reaches American AAdvantage at 1:1. For Citi-anchored travelers, AAdvantage opens Cathay First (110k AA), Qatar QSuite (70k AA), JAL Sky Suite (60k AA off-peak). For Amex-anchored travelers, broader partner depth provides flexibility. Here is the head-to-head.
