Yes, you can transfer Avios between several major international airlines because they share the same mileage currency. In 2026, you can move Avios 1:1 between British Airways, Iberia, Aer Lingus, Qatar Airways, and Finnair. This "Combine My Avios" feature is a powerful tool for travelers looking to book specific "sweet spot" awards—for example, transferring points from British Airways to Qatar Airways to book their famous QSuites. To initiate a transfer, you must have accounts in both programs with matching personal details (name and birthdate). However, a new "30-Day Rule" implemented in early 2026 requires that accounts be open for at least 30 days before they are eligible for transfers. Additionally, transfers to or from Qatar Airways now require a mandatory Two-Factor Authentication (2FA) and a one-time identity verification step where you must upload a photo of your ID. While you cannot transfer Avios directly to other alliance partners like American Airlines, you can use your Avios to book flights on those airlines through the British Airways or Qatar Airways portals, effectively giving you global reach with a single currency.
