Statistics make for nasty college classes but are great for predicting the likelihood that a particular flight, route, or airline will be delayed. Now, I wouldn’t plan my trip based on AvoidDelays.com, but it might be useful for when you are picking up a friend or family member.

For real time flight tracking (only within US airspace) don’t forget FlightAware.
