Google's Flight Search optimized for mobile browsers
The mobile version of the page preserves the table form of the results, but formats them to fit the aspect ratio of today’s smartphones. Filtering of the results is accomplished by drop-down menus that expand from clearly marked buttons, and tapping on the Places push pin icon takes you to a map of your flight – that’s probably not so important if you are flying to San Francisco or Tokyo, but if you are tying to book a flight to a regional airport you aren’t familiar with it never hurts to make sure you have the correct place selected!
The mobile site is available to all iOS and Android devices. You can read more about the UI changes at the source link, or point your mobile browser over to Flight Search if you want to
