Here's my problem (going with one of the examples quoted, flying from Buenes Aires to Toronto): one of the suggestions is to fly to Montreal and take a bus. But what if I _don't_ want the hassle of going from airport to greyhound to bus, only to be dropped into the middle of T'o in the middle of the night? As it stands currently, I can get a refund only if I can find a cheaper flight; but in many cases it's hard to beat the price of a shitty flight + slumming it for 12 hours on the road. So you're SOL. That seems to be accounted for with the three 'flexibility' questions contest creators are asked; whether they will fly with any airline including discount airlines, whether they'll consider ground transport to nearby airports, and whether they'll consider multiple stops and long layover times, respectively.
