A great flight. China Southern is a pretty good airline from China. Service is good, seats are comfortable. I can sleep on the plane as well and the ground staff at Shanghai Hongqiao amd Guangzhou airports are very helpful.
The flight to Guangzhou was nice. Here are some photos.
I had this flight in June 2016, to Guangzhou and from Saigon, in and out of Vietnam to LAX.
They are a good airline with good service, nice plane and food, with decent in-flight entertainment.
I got another flight with them now from Saigon to Shanghai.
