Nonstop flight route between Dillon, Montana, United States and Washington, D.C. / Virginia, United States:

About this route:

A direct, nonstop flight between Dillon Airport (DLN), Dillon, Montana, United States and Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States would travel a Great Circle distance of 1,836 miles (or 2,954 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 Dillon Airport and Washington Dulles International Airport, the route shown on this map most likely still appears to be a straight line.

Facts about Dillon Airport (DLN):

• Because of Dillon Airport's high elevation of 5,241 feet, planes must typically fly at a faster airspeed in order to takeoff or land at DLN. Combined with a high temperature, this could make DLN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The furthest airport from Dillon Airport (DLN) is Sir Gaëtan Duval Airport (RRG), which is located 10,660 miles (17,155 kilometers) away in Rodrigues Island, Mauritius.
• The closest airport to Dillon Airport (DLN) is Bert Mooney Airport (BTM), which is located 48 miles (78 kilometers) N of DLN.
• Dillon Airport (DLN) has 2 runways.

Facts about Washington Dulles International Airport (IAD):

• The furthest airport from Washington Dulles International Airport (IAD) is Margaret River Airport (MGV), which is located 11,659 miles (18,763 kilometers) away in Margaret River, Western Australia, Australia.
• 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 main terminal was recognized by the American Institute of Architects in 1966 for its design concept.
• In September 2009, a 121,700 square feet central Transportation Security Administration checkpoint was added on a new security mezzanine level of the main terminal.

• Washington Dulles International Airport (IAD) has 5 runways.
• Since many major domestic and international airlines have a large presence at Washington Dulles, there are several airline lounges in active operation there.
• 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.
• 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.
