“FlyOnTime.us is a free resource for air travelers and anyone else interested in the on-time performance of the commercial air system in the United States. The flight and weather information presented on this website is derived from data provided by the United States federal government, while the security line times are submitted by visitors like you. This website has four goals:

1. Help American air travelers find the most on-time flights.
2. Help the American public understand the data from government sources by presenting it in interesting and attractive ways. For example, look at statistics for BWI airport, flights from PHL to ORD, Northwest Airlines, cancellations by airport, or airline percent on-time.
3. Tap the wisdom of crowds to collect data on airport security line delays.
4. Allow developers to access flight on-time data in a simple, programmatic way. See more at the developers page.”
