Nonstop flight route between Washington, D.C. / Virginia, United States and St. Catharines, Ontario, Canada:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and St. Catharines/Niagara District Airport (YCM), St. Catharines, Ontario, Canada would travel a Great Circle distance of 307 miles (or 494 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 St. Catharines/Niagara District Airport, the route shown on this map most likely still appears to be a straight line.
