Nonstop flight route between Greenville, South Carolina, United States and Alton, Illinois, United States:

About this route:

A direct, nonstop flight between Greenville Downtown Airport (GMU), Greenville, South Carolina, United States and St. Louis Regional Airport (ALN), Alton, Illinois, United States would travel a Great Circle distance of 509 miles (or 819 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 Greenville Downtown Airport and St. Louis Regional Airport, the route shown on this map most likely still appears to be a straight line.
