Nonstop flight route between Washington, D.C. / Virginia, United States and St. Louis, Missouri, United States:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Lambert–St. Louis International Airport (STL), St. Louis, Missouri, United States would travel a Great Circle distance of 694 miles (or 1,117 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 Washington Dulles International Airport and Lambert–St. Louis International Airport, the route shown on this map most likely still appears to be a straight line.

Facts about Washington Dulles International Airport (IAD):

• The C and D concourses, completed in 1983 and designed by Hellmuth, Obata and Kassabaum, were originally designed as a temporary base for United Airlines, which began hub operations at the airport in 1985.
• A new and permanent C/D concourse is planned as part of the D2 Dulles Development Project.
• 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.
• Washington Dulles International Airport (IAD) has 5 runways.
• 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.
• 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.
• The civil engineering firm Ammann and Whitney was named lead contractor.
• 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 Lambert–St. Louis International Airport's relatively low elevation of 605 feet, planes can take off or land at Lambert–St. Louis 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.
• However, TWA faced increasing problems as overall airline demand softened in response to a softening overall economy.
