Google may have updated its flight search tool for tablets just a couple of months back, but it's been a while since its desktop counterpart saw a refresh. Currently being tested under the call sign "Flight Explorer", the outfit has a new offering that provides a more customizable and visual interface to help root out a suitable plane ticket. While the filters are pretty much the same as the existing Google Flights search engine, there's a new slider to choose trip length, an upfront indication of the best available ticket price for the selected timeframe, along with handy graphs that show price over time, and which yield up specifics when you hover over them with your mouse pointer. There's every chance that these new additions will be merged into Google Flights once any crinkles have been ironed out, but in the meantime there's nothing to stop you using it at the link below. And hey, send us a postcard!
