Nonstop flight route between Alton, Illinois, United States and Cologne, North Rhine-Westphalia, Germany:

About this route:

A direct, nonstop flight between St. Louis Regional Airport (ALN), Alton, Illinois, United States and Cologne/Bonn Airport (CGN), Cologne, North Rhine-Westphalia, Germany would travel a Great Circle distance of 4,478 miles (or 7,207 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 St. Louis Regional Airport and Cologne/Bonn 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 St. Louis Regional Airport and Cologne/Bonn Airport. You'll see that it will travel the same route of the red line on this map!
