How about Hainan Airlines?

I just want to say that Hainan Airlines is the most delayed of so many flights! 10 times, 9.5 times late! Usually two hours at a time. Then there is no answer! Even do the same sales behavior on the plane as on the train! Of course, eloquence is definitely not as good as the population selling things on the train! In an instant, I felt that I had bought a train ticket! I will never buy a Hainan Airlines ticket again!
