In 2026, Avios (the loyalty currency for British Airways, Qatar Airways, and others) remain valid for 36 months from your last activity. This means that as long as you earn or spend at least one Avios point every three years, your entire balance remains a high-value asset. High-quality activities that "reset" the clock include taking a flight, using an Avios-branded credit card, or even shopping through a partner portal. Interestingly, for members of a British Airways Household Account, the presence of a Silver, Gold, or Bronze member protects the points of everyone in the household from expiry, regardless of their individual activity levels. For 2026 collectors, the 36-month window is quite generous, making Avios a premier "long-term" currency for saving toward high-value flight upgrades or "Reward Flight" redemptions, provided you maintain a high-quality habit of engaging with the program at least once every three years.
