Nonstop flight route between Xining, Qinghai, China and West Chicago, Illinois, United States:

About this route:

A direct, nonstop flight between Xining Caojiabao Airport (XNN), Xining, Qinghai, China and DuPage Airport (DPA), West Chicago, Illinois, United States would travel a Great Circle distance of 6,979 miles (or 11,231 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 Xining Caojiabao Airport and DuPage 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 Xining Caojiabao Airport and DuPage Airport. You'll see that it will travel the same route of the red line on this map!

Combined with a high temperature, this could make XNN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• Xining Caojiabao Airport handled 2,030,378 passengers last year.
• Xining Caojiabao Airport (XNN) currently has only 1 runway.
• In addition to being known as "Xining Caojiabao Airport", other names for XNN include "西宁曹家堡机场" and "Xīníng Cáojiābǎo Jīchǎng".
