Nonstop flight route between Washington, D.C. / Virginia, United States and Tanacross, Alaska, United States:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Tanacross Airport (TSG), Tanacross, Alaska, United States would travel a Great Circle distance of 3,125 miles (or 5,029 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 Tanacross 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 Tanacross 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):

• Washington Dulles Airport is the busiest airport in the Washington metropolitan area, and second busiest airport in the larger Baltimore–Washington metropolitan area with over 22 million passengers a year.
• Loudoun County Transit provides a bus service which runs from the Dulles Town Center shopping center, to the airport, then to the Steven F.
• 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.
• 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.
• 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 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.
