After entering the school, you will sign a training agreement with the airline, and you will know which airline you will go to in the future. In the past, only three major airlines could fly independently, but now they need to cooperate with schools and enterprises to fly. If it is purely a school move, which airline to assign depends on the school arrangement.

Central airlines include China, China Eastern Airlines and China Southern Airlines, while private airlines include Hainan Airlines, Sichuan Airlines, Happiness Airlines, Auspicious Airlines, Okay Airlines and many others, but the company's shares are very complicated. For example, Air China owns Shandong Airlines and Shenzhen Airlines, and China Eastern Airlines owns China United Airlines and Shanghai Airlines.
