Chase points can still get you on American Airlines via partner programs

American Airlines AAdvantage is not a direct Chase Ultimate Rewards transfer partner, but travelers can still use Chase points for American flights through Oneworld alliance partners. Three Avios-based programs—Aer Lingus AerClub, British Airways Club, and Iberia Club—accept Chase transfers at a 1:1 ratio and can book American-operated award flights. Each program may offer different award rates, taxes, and availability for the same routes.
