Nonstop flight route between Cologne, North Rhine-Westphalia, Germany and Denver, Colorado, United States:

About this route:

A direct, nonstop flight between Cologne/Bonn Airport (CGN), Cologne, North Rhine-Westphalia, Germany and Denver International Airport (DEN), Denver, Colorado, United States would travel a Great Circle distance of 4,941 miles (or 7,952 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 Cologne/Bonn Airport and Denver International 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 Cologne/Bonn Airport and Denver International Airport. You'll see that it will travel the same route of the red line on this map!

This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.

• Because of Denver International Airport's high elevation of 5,431 feet, planes must typically fly at a faster airspeed in order to takeoff or land at DEN. Combined with a high temperature, this could make DEN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
