Find the lowest fare out there

Farecast.com is the first airfare prediction website.

They help with that bothersome question, "Buy now or wait?"

Farecast offers airfare predictions from more than 75 U.S. departure cities to top domestic destinations.

It's not Orbitz, Travelocity or Expedia. Here's what they do:

Tell travelers if fares are rising or dropping. Based on their predictions, they provide a recommendation to buy now or buy later.

Help travelers buy directly through the airlines' websites.

I have yet to try it, but next time I'm in the market for purchasing an airline ticket, I'll go to their website.
