Yes, that is a big change! Does anyone know when that change took effect? For those of us in the U.S., the Terms & Conditions still allow Household Account members to take companions who are not HHA members:
"Companions do not have to be named within a BA Executive Club Household Account. Members can choose to take anyone as a Companion on their redemption voucher booking."

Perhaps the U.S. rules will be changing, too. That would be unfortunate.
