You can start with flight search from the Google search page itself. Put in a query and you will see the Flights link on the left of the page. That takes you into the dedicated Google Flights page. Of course you can directly reach there too by entering the URL. The various options available are pretty self-explanatory. You can make most of them out from the screenshot below.
But to catch just the right flight and also save money in the process, you have to tinker around with the filters available on Google Flights Search. The map suddenly changes when you fill in the destinations. For instance, you can narrow down the results by eliminating the long and expensive flights. The Price and Duration sliders help to do just that. The dots display the concentration of flights for your destination.
Clicking on a flight reveals the time for the return flight and a link to book the flight with the help of the airline’s site.
Looks pretty neat…but like a lot of recent Google launches, the refurbished Google Flights is only available for the U.S. and it only displays flight schedules for round trip economy class flights. But it’s still worthwhile because it showcases Google’s attempts to integrate travel features alongside the usual search tools.
