Yes, you can absolutely convert American Express Membership Rewards points into Avios points, which is the currency used by British Airways, Qatar Airways, and Iberia. In 2026, the standard conversion rate for many regions is 1 Membership Rewards point to 1 Avios, though some markets may have a 3:2 ratio. The transfer is usually instantaneous, although you should allow up to 48 hours for the points to appear in your airline account. To do this, you must first link your frequent flyer account to your Amex portal. A "pro-tip" for savvy travelers is to look out for transfer bonuses; Amex occasionally offers limited-time promotions where you might receive 20% to 30% more Avios for your points. Additionally, if you have a co-branded British Airways American Express card, you earn Avios directly on your spend. It is one of the most flexible ways to book "Reward Flights" and can offer significant value, especially when used for Business Class (Club World) upgrades or short-haul "Reward Flight Saver" hops across Europe.
