I am a die-hard fan of Google Maps (previous version). For a long time, I played with its API and wrote several applications. Although I don’t like much the new Google Maps, I discover that it shows flights as direction! Google Flight (https://www.google.com/flights/) is a such a cool and über useful tool that you can plan a multi-city trip. I am really impressed with that! It even suggests nearby airports and day alternatives to save your pennies. Good job Big Brother 🙂
