I just converted my account to a household account to include my wife. No reason to add my kids for now, as far as I can see.

So hopefully we'll each get cards, get some coins, and get our 200K miles and some companion tickets. Looks pretty good!

As an aside, I don't think I've ever flown BA, but considering my one and only trip on RyanAir, I'd be more than happy to patronize their rival.
