Farecast offers a unique service by providing its users with intelligent airfare predictions. Founded in 2003, Farecast has since gained very healthy funding from several venture funds totaling $20.6 million. Unlike other travel companies, Farecast predicts when a user should buy a ticket based upon 175 billion points of previous airfare data. Its engine can currently predict whether airfare goes up or down up to a week into the future with a claimed success rate of 70-75%. While Farecast has a lot of competition, they claim it is the only company which can predict future prices.

The site has recently expanded to providing the best deals on hotel room as well. Results from travel search sites like ReserveTravel, Orbitz, and CheapTicket, are shown on a map with prices and other hotel information. Farecase gives deal finders an idea if a specific hotel is overpriced or a good deal by marking overpriced hotels blue and attractively-priced hotels red.
