Looking for the best deal on a flight? A new Google Flights feature might be able to help.
And it means a lot less frustration for those who have looked up prices for a flight only to check again days later and find a higher rate.
Google's new feature will predict fare changes and notify users about price changes for flights they're interested in.
"After selecting a specific flight, a notification may appear letting you know when the current fare is expected to expire and how much you can save if you book now," Google Flights product manager Nabil Naghdy wrote in a blog post.
The feature uses historical flight data to make predictions.
Searching for flights between cities but don't have concrete dates?
A "Tips" feature recommends alternate airports and dates to help travelers find the best price for a route.
Plus, if a customer isn't quite ready to enter his or her card information, the traveler can choose to track a flight or route and receive notifications via email with updates of prices changes and expected price changes.
Google has said the new feature will be available "in the coming weeks."
