Nonstop flight route between Arlington County, Virginia (near Washington, D.C.), United States and San Antonio Oeste, Argentina:

About this route:

A direct, nonstop flight between Ronald Reagan Washington National Airport (DCA), Arlington County, Virginia (near Washington, D.C.), United States and Antoine de Saint Exupéry Airport (OES), San Antonio Oeste, Argentina would travel a Great Circle distance of 5,552 miles (or 8,935 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 Ronald Reagan Washington National Airport and Antoine de Saint Exupéry 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 Ronald Reagan Washington National Airport and Antoine de Saint Exupéry Airport. You'll see that it will travel the same route of the red line on this map!
