Farecast

This online travel website offers something unique – data on the best time to purchase a particular airfare. This way, you can decide to wait and purchase when you know the price is going to drop. This is probably pretty helpful with seasonal destinations like the Caribbean or Ski Resorts. It’s still a beta, but works pretty well. They have some things to sort out – but there are some interesting graphics and data. Who knows – maybe you can get a better deal next week?
