How we figure this out
Distance is the great-circle distance between the two airports, the shortest path over the curved Earth. Flight time assumes an average airliner speed of about 500 mph plus about 30 minutes for taxi, takeoff and landing. The list of facilities follows the same path, using each airport's tower and approach control and the FAA's en route center boundaries.
