On BA they crew do not know if you are on a reward ticket or if you have used miles or a voucher to upgrade.
They do kow if you have been bumped up due to over selling.</font>
Ah, so you could theoretically upgrade twice (since they didn't know you upgraded the first time)? I mean that you could do an award upgrade ahead of time, and then the paid inflight upgrade on top of that? (My understanding -- correct me if I'm wrong -- is that each upgrade can only be used to take you up one class, so this trick would seem to be a way to upgrade two classes, tho of course only if each is available at their separate times.)
