during the last three days i had three flights with them:
PEK-CGO B737 in F (this is what they call it it is c class)
CGO-PEK B737 in F (this is what they call it it is c class)
PEK-Shanghai (Hong Qiao) B747 in C (Upperdeck)
Waht I have to say: very friendly stuff, refurbished aircrafts, cold drinks, chinese food (not bad at all), ..
Overall: why not! Itīs OK!
