About this route:
A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Cowley Airport (YYM), Cowley, Alberta, Canada would travel a Great Circle distance of 1,933 miles (or 3,111 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 Cowley Airport, the route shown on this map most likely still appears to be a straight line.

Facts about Washington Dulles International Airport (IAD):
- 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.
- Under the development plan, future phases would see the addition of several new midfield concourses and a new south terminal.
- Since many major domestic and international airlines have a large presence at Washington Dulles, there are several airline lounges in active operation there.
- 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.
