This is another Chinese domestic airline, that, too operates a member of the 737 family like my last 2 feature requests. There is a lack of Chinese representation in IF, so I am trying to help compensate.
9 Air is a Chinese airline based in Guangzhou that operates entirely domestic flights, except for one to Bangkok.
The 737-800 is a medium range, narrow body aircraft produced by Boeing. It is the most popular commercial aircraft ever built.
