About this route:
A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and James M. Cox Dayton International Airport (DAY), Dayton, Ohio, United States would travel a Great Circle distance of 367 miles (or 590 kilometers).
A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the relatively short distance between Washington Dulles International Airport and James M. Cox Dayton International Airport, the route shown on this map most likely still appears to be a straight line.

Facts about Washington Dulles International Airport (IAD):
- A new and permanent C/D concourse is planned as part of the D2 Dulles Development Project.
- Because of Washington Dulles International Airport's relatively low elevation of 313 feet, planes can take off or land at Washington Dulles International Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
- Conceived in early planning sessions in 1959, Dulles is one of the few remaining airports to use the mobile lounge for boarding and disembarkation from aircraft, and to transfer passengers between the midfield concourses and to and from the main terminal building.
- At the end of World War II, growth in aviation and in the Washington metropolitan area led Congress to pass the Washington Airport Act of 1950, providing federal backing for a second airport.

- A new train system, dubbed AeroTrain and developed by Mitsubishi, began in 2010 to transport passengers between the concourses and the main terminal.
