Which is better, Hainan Airlines or Xiamen Airlines?

HNA is three bases in Beijing, Shanghai and Shenzhen, with a wide range of routes, which can take into account both domestic and foreign. Compared with other airlines, HNA's business class is more conscientious. There is no dentist's bed in business class, and all wide-body business classes can lie flat 180 degrees. In addition, the average age of HNA is very low, and there are no old models. Xiamen Airlines, which is controlled by China Southern Airlines, pays attention to providing high-quality, safe and comfortable services and has won a good reputation. However, from the aspects of route coverage, business class design and aircraft age, HNA has more advantages, so HNA is better than Xiamen Airlines.
