Nonstop flight route between Denver, Colorado, United States and Washington, D.C. / Virginia, United States:

About this route:

A direct, nonstop flight between Denver International Airport (DEN), Denver, Colorado, United States and Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States would travel a Great Circle distance of 1,449 miles (or 2,332 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 Denver International Airport and Washington Dulles International Airport, the route shown on this map most likely still appears to be a straight line.

Facts about Denver International Airport (DEN):

• Jeppesen Terminal's internationally recognized peaked roof, designed by Fentress Bradburn Architects, is reflective of snow-capped mountains and evokes the early history of Colorado when Native American teepees were located across the Great Plains.
• The closest airport to Denver International Airport (DEN) is Centennial Airport (APA), which is located 22 miles (36 kilometers) SSW of DEN.
• At 35,000 acres, DIA is by far the largest land area commercial airport in the United States.
• The furthest airport from Denver International Airport (DEN) is Sir Gaëtan Duval Airport (RRG), which is located 10,877 miles (17,505 kilometers) away in Rodrigues Island, Mauritius.
• Denver International Airport is the main hub for low-cost carrier Frontier Airlines and commuter carrier Great Lakes Airlines.
• From 1980 to 1983, the Denver Regional Council of Governments investigated six areas for a new metro area airport which were north and east of Denver.
• The system's $186 million original construction costs grew by $1 million per day during months of modifications and repairs.
• Denver International Airport handled 52,556,359 passengers last year.
• The airport is 25 miles driving distance from downtown Denver, which is 19 miles further away than Stapleton International Airport, the airport it replaced.
• Because of Denver International Airport's high elevation of 5,431 feet, planes must typically fly at a faster airspeed in order to takeoff or land at DEN. Combined with a high temperature, this could make DEN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• Denver International Airport (DEN) has 6 runways.
• Delays caused by poor planning and repeated design changes due to changing requirements from United Airlines caused Mayor Webb to push opening day back, first to December 1993, then to March 1994.

• As of 2012, the only Washington Metropolitan Area Transit Authority service to Dulles is the "Express" 5A Metrobus route.
• 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.
