No, Avios points cannot be used on all airlines, but they are exceptionally versatile through the oneworld® alliance and specific partner agreements. You can use Avios primarily on British Airways, Iberia, Aer Lingus, Vueling, and Qatar Airways, as these airlines use Avios as their direct currency. Additionally, you can redeem them for flights on any of the 13 oneworld member airlines, including American Airlines, Alaska Airlines, Cathay Pacific, Qantas, and Japan Airlines. In 2026, the partnership with Qatar Airways and Finnair has made it even easier to "link" accounts and move Avios between programs to find the best redemption rates, but you generally cannot use them for non-partner airlines like Delta, United, or Emirates.
