Google's ITA Software blog just posted some information highlighting the best features of Google Flight Search.
If you're not ready to book your flight immediately, you can save the information and easily access it all later when you're ready to book it. To save a flight, you can hit the star icon, and you can access these flights again later by hitting the star icon again when you're on the flight search home page. Any price changes or availability details will be reflected in the saved information as well.
It's definitely a handy little tool that can be used when searching for flights on the go.
