First, the plane was clean, comfortable, great inflation movies/entertainment, decent food and attention friends m flight attendants. The flavor got experience was good. Would fly them again.
Now a caveat for travelers who may not obsessively check emails, paperwork, visas, etc. China Southern DOES check obsessively. If your paperwork isn’t exact you will NOT fly...which means your subsequent return plans are in flux. They’re Not being jerks. They follow the rules exactly. (Especially if you are western)
Again...clean, decent food, service, entertainment...just make sure YOU have taken care of your documents because no favors will be given.
