Hi - I know you can transfer Avios miles to other members of your household account for free, but can anyone tell me how to do this online? When logged into my account, I click the link to "Share Avios" but the only option seems to be to transfer to non-household members online (which requires a fee). I've also clicked on the link to Manage My Household Account but there doesn't seem to be any option there either to transfer Avios miles. Perhaps I'm being a little dense

, but it really does not seem obvious from the BA website how I can do this? If anyone could help, I'd really appreciate it! Thank you so much!
