Nonstop flight route between Washington, D.C. / Virginia, United States and Hilo, Hawaii, United States:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Hilo International Airport (ITO), Hilo, Hawaii, United States would travel a Great Circle distance of 4,721 miles (or 7,597 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 large distance between Washington Dulles International Airport and Hilo International Airport, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Washington Dulles International Airport and Hilo International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Washington Dulles International Airport (IAD):

• The main terminal was extended in 1996 to 1,240 feet —Saarinen's original design length—which was slightly more than double its originally constructed length of 600 feet.
• 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.
• 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.
• 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.
• Construction is now underway to connect the airport to Washington via the Silver Line of the Washington Metro.
