I don't use You First. Well, I've tried at least, by emailing them trying to reserve a cabana next month as I'm coming in from Amsterdam on KLM on a separate ticket (very early in the morning) and would like a shower, a nap for an hour and a quiet place to make a few phone calls. I noted in my email that I was taking note of the fact that "You First is for UK residents who have booked a flight in First that is operated by British Airways". (Which makes those of us, at least with BAEC profiles in Europe, feel decidedly You Second.) However, You First never got back to me -- either because using a GUF2 on a Club ticket doesn't qualify as booking a flight in First per se, or I'm foreign muck.
