Nonstop flight route between Ust-Kut, Irkutsk Oblast, Russia and Alton, Illinois, United States:

About this route:

A direct, nonstop flight between Ust-Kut Airport (UKX), Ust-Kut, Irkutsk Oblast, Russia and St. Louis Regional Airport (ALN), Alton, Illinois, United States would travel a Great Circle distance of 5,757 miles (or 9,266 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 Ust-Kut Airport and St. Louis Regional 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 Ust-Kut Airport and St. Louis Regional Airport. You'll see that it will travel the same route of the red line on this map!
