Why is it that sometimes I can wait until the last minute and find a cheap fare, but other times the fare goes up?
Well, most of the time the fare will go up because the flight will be filling up or the advance purchase restrictions will be kicking in. But on routes with significant competition -- New York to Los Angeles for example -- airlines may have sales or "dump seats" at the last minute to fill the plane if it's not particularly full. It also depends on the day of the week. Tuesday, Wednesday and Saturday are often the cheapest days to fly because we carry fewer business passengers those days.
