You cannot technically "merge" two separate Avios accounts into one single permanent identity, but in 2026, you can achieve the same result using a Household Account. British Airways allows up to seven people living at the same address to link their Executive Club accounts. Once linked, the Avios from all members are "pooled" into a collective balance that can be used to book flights for anyone in the household. Additionally, you can "Combine my Avios" across different programs; for example, if you have Avios in Qatar Airways Privilege Club, Iberia Plus, and British Airways Executive Club, you can move them freely between these accounts at a 1:1 ratio using the "linked accounts" feature on their respective websites. This is particularly useful because some airlines offer lower "award taxes" or different seat availability. While each person must maintain their own unique membership number for earning purposes (you cannot earn points for a flight on someone else's number), the pooling and transferring features make managing a family's "Avios bank" almost seamless.
