Yes, Avios can be used on Qatar Airways, and as of 2022, Qatar Airways' loyalty program, the Privilege Club, officially adopted Avios as its reward currency. This move created a "seamless" ecosystem between Qatar Airways, British Airways, Iberia, Aer Lingus, and Vueling. You can link your British Airways Executive Club account to your Qatar Airways Privilege Club account and move your Avios back and forth instantly at a 1:1 ratio. This is particularly valuable because it gives you access to book Qatar’s world-renowned Qsuite (Business Class) using points. Booking through the Qatar Airways website often yields better availability and lower taxes/fees for their own flights compared to booking a "Partner Award" through the British Airways website. You can also use Avios for "Part Payment" on cash tickets or for cabin upgrades on Qatar-operated flights. This integration has made Avios one of the most flexible and powerful airline currencies in the world, allowing travelers to leverage the massive combined network of the oneworld alliance. To get started, you simply need to create a Privilege Club account and use the "Link My Accounts" feature available on either the BA or Qatar Airways dashboards to sync your balances.
