Global air passengers set to double by 2038

As China has become the world's second-largest aviation market, limited capacity has become a major bottleneck for many domestic airports, which are rushing to better tap their physical and digital resources.

The International Air Transport Association forecast that global passenger numbers will double in the next 20 years to 7.8 billion people, with half of all new passengers coming from the Asia-Pacific region, to which China will be a large contributor.

Wang Zhiqing, deputy administrator of the Civil Aviation Administration of China, estimated the number of outbound Chinese tourists will exceed 700 million in the next few years.
