Join me to fly to the World's Highest Airport - Daocheng Yading Airport in China. Daocheng (DCY) airport is in the Western part of China at 4,411m (14,472 ft). Daocheng is the highest commercial airport in the world. Sichuan Airlines fly to Daocheng from Chengdu regularly on their A319.
I was able to go to the cockpit to interview the captain about the difficulties of flying into this high altitude airports. The crew require to wear oxygen masks during flight critical times (takeoff/landing) at Daocheng. Currently 6 out of World's top 10 airports is in China.
