About this route:
A direct, nonstop flight between St. Louis Regional Airport (ALN), Alton, Illinois, United States and Denver International Airport (DEN), Denver, Colorado, United States would travel a Great Circle distance of 783 miles (or 1,260 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 St. Louis Regional Airport and Denver International Airport, the route shown on this map most likely still appears to be a straight line.

- Because of St. Louis Regional Airport's relatively low elevation of 544 feet, planes can take off or land at St. Louis Regional Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
- Its operations are paid for by an airport taxation district created in 1946, which collects taxes from property owners in the Madison County townships of Alton, Wood River, Foster and Fort Russell.
