Ditto w/ account password reset...
In the interests of research I've just tried to reset a BA account password using an e-mail address to log in - and I received an e-mail for one of the seven members of the BA Household Accounts (HHA) of which I am the head. Not mine, but the most recently-added member.
But then again, I always sign into my BA, UA and HHonors accounts with individual membership numbers; unlike e-mail addresses (at least in the case of BA and UA), individual membership numbers are unique.
So maybe I should re-phrase my original question - why do BA and UA allow multiple members to use the same e-mail address, while HHonors does not?
