CAAC suggested in its draft implementation plan for accelerating air Internet access that all domestic aviation departments complete 60% of the overall plan for air Internet access services by the end of 2020 and strive to cover the entire fleet by 2022. Feng zhenglin, deputy general of CAAC, also said at this year's National People's Congress and the Chinese Political Consultative Conference that he would continue to promote in-flight wi-fi technology in the coming years. For airlines, developing in-flight wi-fi is a trend. On the other hand, China is the world's second largest aviation market. According to the prediction of IATA, China will overtake the United States as the world's largest aviation market around 2022. In the face of such a huge market, in-flight wi-fi has not only become a "good to have" to enhance the passenger experience and strengthen the loyalty of frequent fliers, but also become a new blue ocean of profits and a "must have" for major domestic airlines in the context of soaring oil prices and white-hot competition. In just two years, more than 2,000 aircraft in China will be equipped with in-flight wi-fi, doubling in three years. Based on the size of the new civil aviation aircraft in China, the size of the fleet in 2022 will approach 5,000 . New equipment and the demand of the system is only a small piece of the market, China civil aviation transportation passenger quantity has 610 million visitors in 2018, If the average person flies 2.5 hours, that's more than 1.5 billion hours a year, who can attract this group of high quality flight passengers fly time , then open up a vast market will undoubtedly.
