Google Flights Beta
Google has released a beta version of Google flights. The new version can be found at https://www.google.com/flights/beta
The search tool allows you to search for one way,return or even multi city trips. Sort by price,flight duration or departure time. You can limit the search to different airlines or alliances.
You can even save and track searches if you aren’t sure if the current price is the best. Saved search will show a price history to see if prices are climbing or falling.
In addition to the obvious search tools there is a map option allowing you to click on cities. The map allows you to see any cheap cities from your selected departure airport. Useful if you’re looking for a cheap weekend getaway and aren’t sure of which destination to pick. Or if you want to compare nearby airports to see if they’re more convenient.
The older classic version of the search tool is still available at https://www.google.com/flights/
You can compare the two versions yourself seeing which you like best
