I want to gift Avios to someone who is a member of a Household account. Where will the Avios go?

Gifted Avios will be added to the balance of the person you bought it for.

If the recipient is a member of a Household account, their balance will be pooled with the other members of the Household.

Any member of a Household can redeem Avios from the Household account, the amount of Avios will be taken from individual members’ balance on a pro-rata basis.
