Many of us may be thinking of Nepal, but the highest airports in the world are mostly in China. Nine out of ten are located in the territory of the "Land of the Dragon". These infrastructures are fundamental because they offer a long-range transport service to communities living at prohibitive altitudes, around 4000 meters and above, where the conformation of the territory makes it more difficult, if not impossible, to move from one place to another. 

The highest airport in the world is Daocheng Yading, China. Inaugurated in September 2013, it was built at an altitude of 4411 meters, in Sichuan province, in the south-west of the country. The stopover has a single runway, 4200 meters long and 45 meters wide, and a 5000 square meter terminal. Due to its high altitude, pilots follow special procedures for takeoffs and landings, and passengers must acclimatize before flying. 

In second place, among the highest airports in the world, is Changdu Bangda airport, which is located in the Tibet region at an altitude of 4334 meters, exposed to a constant wind of up to 30 meters per second and with temperatures down to -20°C. On the last step of the podium in this special ranking is the Rikaze Dingri airport, located at 4300 meters, also in the Chinese autonomous region of Tibet.
