How Does KAYAK’s Price Forecast Work?


Our goal has always been to provide travelers with the information they need. So, in 2013, we launched our Price Forecast tool to help you book with confidence.

This tools uses data from over 1.5 billion annual searches on KAYAK to help predict whether you should wait or book your flight now by looking at price trends and historical price data. It’s something that helps take the guesswork out of “is now the right time to book my flight?” and helps guide you towards a more confident decision. A “Wait” recommendation means that we don’t foresee prices going up over the next several days. A “Buy” recommendation means prices are likely to rise. It’s as simple as that.

And while the easiest way to use our Price Forecast tool is to kick off a flight search, we’ve also incorporated it into our Price Alerts. Sometimes, if we’ve got really solid data on a route, we’ll let you know when we alert you about price changes.

To learn more about how we make Price Forecasts, check out our Price Trends & Tips then head over to our Flight Search to try it out.

Just remember: like any forecast, our recommendation can’t be guaranteed. We always say, if you think you’ve found a good deal — book it. To know what’s considered a good deal to your destination, try out our Anywhere tool.
