The Capital One mileage program has just introduced a 20% transfer bonus to British Airways Club, valid through October 31, 2026. This has the potential to be a good deal, and this offer doesn’t come around often.

Between October 1 and October 31, 2026, it’s possible to receive a 20% bonus when you transfer miles from Capital One to the British Airways Club program. This promotion is being offered on Capital One’s end, so you should see the bonus at the time that you make the transfer.

The transfer ratio is usually 1:1, so through this promotion you can transfer miles at a 1,000:1,200 ratio. The 20% bonus should post at the same time as the standard rewards. There’s no registration required, and no limit to how many bonus points you can earn. Transfers from Capital One to British Airways are generally instant .

We see bonuses from various transferable points currencies to British Airways fairly often, typically in the range of 20-40%. We last saw Capital One offer a transfer bonus to British Airways around the same time last year, also for a 20% bonus. So for Capital One to British Airways transfers, this is as good as it gets.

I think there’s value to be had in taking advantage of a 20% bonus on points transfers from Capital One to British Airways Club. Keep in mind that you can transfer points between the various “flavors” of Avios , as this is also the currency of Aer Lingus AerClub, Finnair Plus, Iberia Club, and Qatar Airways Privilege Club.

Back in the day, the best uses of British Airways Avios were for short haul travel on partner airlines, including on Alaska and American. Unfortunately those redemption opportunities have been devalued horribly .

However, lots of great new options using Avios have emerged. For example, I love how Qatar Airways Privilege Club is now an Avios airline, as this opens up some great opportunities. Qatar Airways has one of the world’s best business class products, and the airline makes a vast majority of business class award space available only to those redeeming Avios. Even then, though, availability isn’t exactly great.

Anyway, there’s a ton of potential value here, so see my guides to maximizing Avios with British Airways Club , Iberia Club , Aer Lingus Aer Club , Qatar Airways Privilege Club , and Finnair Plus .
