Avios points only expire if there is no activity on your account for 36 consecutive months. "Activity" is defined very broadly in 2026: you don't necessarily have to fly to keep your balance alive. Simply earning, spending, sharing, or even "buying" a single Avios point will reset the three-year clock for your entire balance. This makes it very easy to protect your points; you can keep them active by using the British Airways Executive Club shopping portal to buy a small item, linking your account to a partner like Uber or BP, or even converting a few Nectar points into Avios. If you have a co-branded credit card, your monthly spending automatically keeps your account "active." It is a high-value strategy to set a "calendar reminder" for every 30 months just to check your balance, as losing a large stash of points due to 36 months of total inactivity is one of the most avoidable mistakes in the points-and-miles world. As long as you interact with the program at least once every three years, your Avios are essentially "immortal."
