Wouldn't it be nice if someone could tell you what your travel date or time should be in order to get the best fare? That's what Farecast is for. It processes millions of round-trip, flight itineraries from airfare information sources, such as Expedia and Priceline, and tells you when the best fares are expected to become available. Farecast has developed technology that can identify patterns based on past airfare data that’s associated with significant price changes. The information is used to predict future airfares in addition to current market conditions. The more expensive fares are filtered out and you get the best hotel and airfare deals in just a few seconds.
