farecast.com does airfare predictions
Farecast.com has just added Nashville to its list of cities that it does airfare predictions for. It doesn’t do a ton of destination cities from Nashville yet, but it seems like a pretty neat idea. It looks at the fares for the dates you want to fly for the last few days to see if they’ve been changing at all, and recommends whether you should buy your ticket now or wait. It also does a grid view where you can find the cheapest time of day to fly. Pretty neat.
