Welcome Kevs! How's life in HKG
? Me going back in 2 weeks time to feel the atmosphere after SARS.
Actually, everytime I transit at Singapore there has to be people asking if there's a chance for upgrading. It's probably because it won't cause any harm anyway by asking cause it won't cost you any money. And not everyone can afford to get a better seating, especially when someone's on a long-haul trip in Y and wants to get into J or even F, that's actually quite understandable.
If flights are overbooked the chance for frequent flyers in Y would get an upgrade would increase, or if there are no frequent flyers the passengers who comes late to the check-in counter would possibily get an upgrade or get an accomodation. Usually however upgrades are quite unpredicted, a friend of mine flew back to YVR
and he got upgraded to J class. Though he was not a frequent flyer......
I think most people won't really take it for granted, they just want to know if there's a chance. Chances are anything is possible, but I'd prefer just letting it be.
