I thought we'd always had OT chatter here. It's a nice community precisely because it's here. I don't think I'd frequent it (or FT) nearly as much without it. (And much the same goes for the other airline forum I read, namely QF.)
Also, Tesco does very much belong here because most of the regular posters are avid collectors of BA Miles via Tesco. (I, of course, continue to be a disgrace. I think I've been all beefed out.)
