Fliion,
I have heard through the grapevine that there are 3-4 carriers only out of the many in china that are worth going to.
Hainan
China Southern
SF Cargo
China Airlines
That is in the order that was given to me. Also, I was told that you get fined for various things there such as not downloading your OFP on time or if you get struck by lightning. Still, I am interested to know more just as you are if anyone can shed more light.
