Nonstop flight route between Washington, D.C. / Virginia, United States and Saint-Louis, Senegal:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Saint-Louis Airport (XLS), Saint-Louis, Senegal would travel a Great Circle distance of 3,978 miles (or 6,402 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 large distance between Washington Dulles International Airport and Saint-Louis Airport, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Washington Dulles International Airport and Saint-Louis Airport. You'll see that it will travel the same route of the red line on this map!
