About this route:
A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Ocean Reef Club Airport (OCA), Key Largo, Florida, United States would travel a Great Circle distance of 956 miles (or 1,538 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 Ocean Reef Club Airport, the route shown on this map most likely still appears to be a straight line.

Facts about Washington Dulles International Airport (IAD):
- The C and D concourses, completed in 1983 and designed by Hellmuth, Obata and Kassabaum, were originally designed as a temporary base for United Airlines, which began hub operations at the airport in 1985.

 - By the 1980s, the original design, which had mobile lounges meet each plane, was no longer well-suited to Dulles' role as a hub airport.
 - The Metropolitan Washington Airports Authority has begun to gradually phase out the mobile lounge system for inter-terminal passenger movements in favor of the AeroTrain, an underground people mover which currently operates to Concourses A, B and C, and a pedestrian walkway system.
