No, as of March 2026, American Express Membership Rewards points do not directly transfer to American Airlines AAdvantage miles. This is due to a long-standing exclusive partnership between American Airlines and Barclays/Citi for their credit card products. To move points to American Airlines, you must use an indirect "workaround." The most common method in 2026 is transferring Amex points to Marriott Bonvoy at a 1:1 ratio, and then transferring those Marriott points to American Airlines at a 3:1 ratio. Alternatively, you can use your Amex points to book American Airlines flights directly through the Amex Travel portal, though this treats points like cash (usually 1 cent per point) rather than a 1:1 mileage transfer. For travelers seeking direct 1:1 airline transfers in the Oneworld alliance, Amex points are better suited for British Airways, Iberia, or Qatar Airways, all of which use the Avios currency and can be used to book "award seats" on American Airlines flights.
