Nonstop flight route between Washington, D.C. / Virginia, United States and Sukhothai, Thailand:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Sukhothai Airport (THS), Sukhothai, Thailand would travel a Great Circle distance of 8,551 miles (or 13,761 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 Sukhothai 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 Sukhothai 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 recognized by the American Institute of Architects in 1966 for its design concept.
• Washington Dulles International Airport (IAD) has 5 runways.
• 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.
• 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.
• 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 closest airport to Washington Dulles International Airport (IAD) is Leesburg Executive Airport (JYO), which is located only 11 miles (17 kilometers) NNW of IAD.
• 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.
• Dulles is accessible via the Dulles Access Road/Dulles Greenway and State Route 28.
• Under the development plan, future phases would see the addition of several new midfield concourses and a new south terminal.

• Sukhothai Airport (THS) currently has only 1 runway.
• Because of Sukhothai Airport's relatively low elevation of 179 feet, planes can take off or land at Sukhothai 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.
