About this route:
A direct, nonstop flight between Jiuzhai Huanglong Airport (JZH), Songpan County, Sichuan, China and St. Mary's Airport (KSM), St. Mary's, Alaska, United States would travel a Great Circle distance of 4,332 miles (or 6,972 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 Jiuzhai Huanglong Airport and St. Mary's 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 Jiuzhai Huanglong Airport and St. Mary's Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Jiuzhai Huanglong Airport (JZH):
- In addition to being known as "Jiuzhai Huanglong Airport", other names for JZH include "九寨黄龙机场" and "Jiǔzhài Huánglóng Jīchǎng".
- Because of Jiuzhai Huanglong Airport's high elevation of 11,312 feet, planes must typically fly at a faster airspeed in order to takeoff or land at JZH. Combined with a high temperature, this could make JZH a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- Jiuzhai Huanglong Airport (JZH) currently has only 1 runway.
- The closest airport to Jiuzhai Huanglong Airport (JZH) is Mianyang Nanjiao Airport (MIG), which is located 116 miles (187 kilometers) SSE of JZH.
- The furthest airport from Jiuzhai Huanglong Airport (JZH) is Viña del Mar Airport (KNA), which is nearly antipodal to Jiuzhai Huanglong Airport (meaning Jiuzhai Huanglong Airport is almost on the exact opposite side of the Earth from Viña del Mar Airport), and is located 12,156 miles (19,563 kilometers) away in Viña del Mar, Chile.

- St. Mary's Airport (KSM) has 2 runways.
- The closest airport to St. Mary's Airport (KSM) is Mountain Village Airport (MOU), which is located only 13 miles (20 kilometers) W of KSM.
- Because of St. Mary's Airport's relatively low elevation of 312 feet, planes can take off or land at St. Mary's Airport at a lower air speed than at airports located at a higher elevation.
