Seriously, ZRH to GVA? Last time I did that flight in Business, they served Business passengers tiny portions of something (I can't remember what) and then saw them snatching it away again before some pax had even started to eat, so short was the flight. I have to say, I don't even look for Business bargains during booking any more, because I don't even book SWISS any more. So I don't know if the extremely cheap upgrades are still being offered or even purchased. Reckon they're not worth much more than 10 or 15 francs, and that's probably being generous.
