Our partnership with British Airways British Airways connects you to nearly 250 destinations in 90 countries around the world from its major hub at London Heathrow. When you fly on British Airways, you can earn and redeem AAdvantage^® miles, plus, enjoy the benefits of your AAdvantage^® status.

Yes, you can absolutely use American Airlines AAdvantage miles to book flights on British Airways, thanks to their shared membership in the oneWorld alliance and a deep "joint business agreement" for transatlantic travel. To do this in 2026, you simply search for your desired destination on the American Airlines website and select the "Redeem Miles" box. The search results will display British Airways-operated flights alongside American's own flights. A major caveat to watch out for is the carrier-imposed surcharges. While the mileage cost might be low (e.g., 30,000 miles for a one-way to London), British Airways often passes on significant "fuel surcharges" and taxes that can exceed $200 for Economy or $700+ for Business Class. These fees are significantly higher than what you would pay if you found an "American Airlines-operated" flight for the same route. Despite the high fees, it is a very popular way to access BA's extensive network through London Heathrow.
