Bejing to Hangzhou flight was full but staff very prompt and efficient. Boarding was quick and plane departed and arrived on time. The cabin crew introduced themselves as soon as the plane levelled out and even bowed during the introduction. Very nice touch. Aircraft was very clean and new 737-800. The overhead tv`s had good entertainment. Food was not to my liking but nobody else in my group complained - so it must be me. The only complaint is that they continue to serve drinks and food when the plane is experiencing turbulence? How is it deemed unsafe to use the WC but its deemed safe to serve hot coffee? Other than that no complaints. Would certainly recommend and will try and fly them again over other domestic airlines in China. They certainly are the only 4star airline I have flown on in China.
