+1. Even if I don't think I will need to change/cancel, this is one thing I will read before booking on any carrier, anytime so I know exactly what change/cancel penalties are.
Most fares ex-US at least will give you credit for unused value - a fee. Some carriers in other regions have fares with no changes allowed at all, and like a pre-paid hotel, if you don't use it for the date you booked, you lose the $ completely.
