As promised, some data on the Civil Aviation industry in China.
----------------------------
In 2002 there were only 4 airports in China with a capacity to handle 10,000,000 passengers a year or more.
By 2011 there were 21 airports with that capacity and the main ones (Beijing, Shanghai, Guangzhou) handle many more
By 2016 (next year), there will be some 230 Airports of at least that capacity.
There is a government estimate that by 2030 China will need another 5000 aircraft.
------------------------
An IATA (International Air Transport Association) report last year forecast that by 2034 flights to, from and within China will account for some 1.3 billion passengers, 856 million more than 2014.
Which places the 2014 figures, as nearly 500 million. The forecast concluded that China will overtake the USA as the world's largest aviation passenger market by 2030.
The above from business magazine, AsiaToday International.

Sort of corroborating that forecast is Boeing's own estimate of the size of the Chinese market:
