Yes, you can absolutely earn Avios points when flying on American Airlines, provided you are a member of a frequent flyer program that uses Avios as its currency, such as the British Airways Executive Club, Iberia Plus, or Qatar Airways Privilege Club. Since American Airlines and British Airways are both founding members of the Oneworld Alliance, they have a deep partnership. When you book an American Airlines flight, you simply enter your British Airways Executive Club number into the reservation. The number of Avios you earn will depend on the distance flown and your fare class (Business and First Class earn significantly more). In 2026, you can also "link" your British Airways and Qatar Airways accounts to move Avios back and forth freely. One important tip for 2026 is that you often get better value by redeeming Avios for American Airlines short-haul domestic flights, as the "Reward Flight Saver" options often provide a high "cent-per-point" value compared to using them on long-haul transatlantic routes that carry high surcharges.
