Nonstop flight route between Ottumwa, Iowa, United States and Kunming, Yunnan, China:

About this route:

A direct, nonstop flight between Ottumwa Regional Airport (OTM), Ottumwa, Iowa, United States and Kunming Changshui International Airport (KMG), Kunming, Yunnan, China would travel a Great Circle distance of 7,757 miles (or 12,484 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 Ottumwa Regional Airport and Kunming Changshui 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 Ottumwa Regional Airport and Kunming Changshui International Airport. You'll see that it will travel the same route of the red line on this map!

• The closest airport to Ottumwa Regional Airport (OTM) is Fairfield Municipal Airport (FFL), which is located 25 miles (40 kilometers) E of OTM.
• Ottumwa Regional Airport covers an area of 1,600 acres at an elevation of 845 feet above mean sea level.
• Because of Ottumwa Regional Airport's relatively low elevation of 845 feet, planes can take off or land at Ottumwa 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.
• Ottumwa Regional Airport (OTM) has 2 runways.
• The furthest airport from Ottumwa Regional Airport (OTM) is Margaret River Airport (MGV), which is located 10,856 miles (17,470 kilometers) away in Margaret River, Western Australia, Australia.

Combined with a high temperature, this could make KMG a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• Kunming Changshui International Airport is the primary airport serving Kunming, the capital of Yunnan Province, China.
• The main terminal was designed by architectural firm SOM with engineering firm Arup.
