A representation of air traffic patterns across the world during a typical 24 hours span using data from delay predictor FlightStats.
It seems as though most flights flow from the US to Europe, then back again. FlightStats is a great way to predict potential delays in advance. If you’re traveling in the US, you can use the the FAA status map or Google hack to find out about current delays and find out how long you’ll be waiting in security lines from the TSA.
