Yes, your wife can transfer her Avios to you, and in 2026, there are several ways to do this depending on the specific airline program. The most common method in the British Airways Executive Club is through a Household Account. This allows up to seven people living at the same address to "pool" their Avios for free, so when you book a flight, the system automatically draws from the total balance of everyone in the household. If you do not want to set up a Household Account, she can use the "Buy, Gift & Transfer" feature on the website, though this typically incurs a fee (often around £25-£50 depending on the amount). Another modern option is through Qatar Airways Privilege Club, which allows "Family Program" members to share Avios seamlessly. Since Avios can now be moved 1:1 between British Airways, Qatar, Iberia, and Aer Lingus, you have significant flexibility. It is important to ensure that the names and addresses on both accounts match exactly to avoid any security flags or delays during the transfer process, which is usually instantaneous once the accounts are linked.
