When booking air travel, the dilemma is often: should I buy now or wait later to try to get a better price?  Now you've got some help. 



The Bing Travel Farecast provides a free airfare prediction tool that allows you to specify your travel dates and destinations, and you'll get a prediction of whether fares for your flight are rising or falling, so you can decide whether you should buy now or wait.



From the Bing website: "According to a third-party audit of our predictive technology, we're about 75% accurate and on average, customers will save over $50 on a typical round-trip transaction."

 

Here are details on Bing's predictive technology.
