Google Flights now gives you early warning of an expected fare increase
By typing Google Flights into the Google search bar on your mobile device, you can type in your destination, the date(s) of travel, and find the best flight for you to take based on travel time, ETA and price. As we said, the notification of an impending price hike on a flight you're researching is based on historical patterns, and includes when the new price might take effect, and by how much the fare should rise based on past increases.
In addition, Google is also updating its Google Hotels feature to make it easier to find consumers a great deal. The service already tells consumers when a particular hotel has rooms available for a price lower than the historical average. Google says that the new features will be rolling out in the coming weeks.
