Yes, in 2026, Qatar Airways and British Airways both use Avios as their primary loyalty currency, and they are essentially "interchangeable." Since Qatar Airways officially adopted Avios in 2022, you can link your British Airways Executive Club account and your Qatar Airways Privilege Club account. This allows you to move your Avios balance back and forth between the two airlines at a 1:1 ratio instantly and for free. This is a massive advantage for 2026 travelers because it allows you to combine points from different credit cards or flights to reach a reward goal faster. For example, you might earn Avios on a flight to London but spend them on a "Qsuite" business class seat to Doha. While the "currency" is the same, each airline maintains its own "award chart" and fees; a peer-to-peer "pro-tip" is to check the price for the same flight on both websites, as one carrier might charge fewer Avios or lower taxes/surcharges for the exact same seat on a codeshare flight.
