Nonstop flight route between Washington, D.C. / Virginia, United States and St. Helens, Tasmania, Australia:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and St Helens Airport (HLS), St. Helens, Tasmania, Australia would travel a Great Circle distance of 10,043 miles (or 16,163 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 St Helens 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 St Helens Airport. You'll see that it will travel the same route of the red line on this map!

• 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.
• 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.
• Washington Dulles International Airport (IAD) has 5 runways.
• Concourse A consists of a permanent ground level set of gates designed for small planes such as regional jets and several former B concourse gates.

This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• 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.
• Under the development plan, future phases would see the addition of several new midfield concourses and a new south terminal.
