Living in Savannah means that whenever I fly, I usually have to make a connection, typically in Atlanta. It's sort of the gateway between the Southeast and the rest of the world. While navigating the world's busiest airport, it's easy to start thinking about global travel.
Gadling recently posted a video that offers more insight on the flow of global travel. In fact, it shows every flight that takes place within a single day and represents them in yellow on a world map.
As night turns to day, the U.S. lights up and the flow of travel begins heading West. As it gets later, those flights head across the Atlantic and so on. The video is a bit mesmerizing but it's interesting to note other travel trends after seeing it a few times.
