Airports are fascinating structures which facilitate movement of millions of people and thousands of tons of commodities. Airports are located all over the world with the majority built within the peripheries of the main cities and towns. However, there are several areas in the world where airports are constructed in extremely high altitudes with the China having six of the top ten highest airports in the world.
1. Daocheng Yading Airport (China)
The Daocheng Yading Airport is an airport located in the Sangdui Township in the Sichuan province of China. The airport serves the Sichuan province and has a capacity of handling 280,000 passengers per year. Constructed in a mountainous region, the Daocheng Yading Airport sits 14,472 feet above sea level and holds the title of the highest airport in the world since its construction in September 16th, 2013 at the cost of $255 million. Three airline companies use the airport and are comprised of Air China, Sichuan Airlines, and the China Eastern Airlines all of which have flights to Chengdu.
2. Qamdo Airport (China)
The Qamdo Airport is a public airport located in the Tibet region of China. Located near the Himalayas at an altitude of 14,219 feet above sea level the Qamdo Airport is the second highest airport in the world. The airport was the highest airport in the world before it was surpassed by the Daocheng Yading Airport. However, the Qamdo Bamda Airport still holds the record of having the longest paved runway of any public airport with its runways stretching 3.4 miles. A second runway is under construction and is expected to be in service by 2018.The airlines which use the Qamdo Bamda Airport are Air China and Tibet Airlines.
3. Kangding Airport (China)
The Kangding Airport is a Chinese airport located in the Tibetan Autonomous Area of Sichuan Province. The Kangding Airport’s construction was undertaken by a Chinese company, Zhongnan Airports Construction Corporation. It commenced in 2006 and was opened on October 18th, 2009 at the cost of $125 million. Built on the Zheduo Mountain, the Kangding Airport is the third highest airport in the world with an elevation of 14,042 feet above sea level.

Conditions At High Altitude Airports
While airports located at high altitudes offer spectacular scenery, the climatic and weather conditions are some of the worst in the world of aviation. The presence of thin air makes the atmospheric pressure extremely low. These conditions make it difficult for an airplane to gain lift. Additionally, less air resistance increases the need for deceleration of an aircraft when landing and hence such airports require longer runways.
