McDoo the Irish Navigator, I've to correct you that Hainan is not a SAR, it is a province of People's Republic of China.
Ivanahumpalot, I also need to correct you as well. In China, there isn't a company or organization is called Hainan Air. I think you made a mistake, the Haikou-based airline carrier is called Hainan Airlines and it is the fourth largest airline group in China. If you would like to know more details, you could simply access Hainan Airlines official web site at
