Since I could not find a three that dealt with this topic, I started a new one. Sorry if this topic has been discussed here, which I am sure, it has been - I just could not find the thread.

I have a British Airways household account that has my son and my wife as members. I collect avios with iberia, my wife with Qatar. In order to book some flights with avios reductions on Iberia, I would like to transfer/ combine my wife's avios to/ with my British Airways account. The goal is to then transfer them to iberia and use them for flights we would like to book. In my world it would look like this:
- we transfer her Avios (they have been combined with the Qatar Privilege account) within our household account to my account
- I transfer theses miles to my Iberia account
- we book iberia flights with the transferred avios

Is that anyhow possible? Are there any restrictions like a certain amount per year and person? Do any charges apply?

Thank you so much!
