Perhaps this should be a separate thread - but by way of example, I am going to Asia soon for a quick weekend, but I'm not sure which country yet - and likely won't decide until a week before based on work (i.e. is midnight flight from Atlanta to Seoul more convenient than a daytime flight from DTW or MSP, etc. etc.)... anything wrong with, let's say for example, having simultaneous reservations in Tokyo, Seoul, Shanghai, and Beijing for the same weekend, and then cancelling three of the four, 2 to 5 days before?
