I can tell u it changes almost daily. before starting my nng-mco trip last week i called CA and they said 32kg plus the 15kg for my being skyteam gold and booking on nwa biz out of can. so out of nng, no problem. but inbound today, i was charged y178 for an extra 11kg, god only knows where she got that number.........and get this..........because I did not have enough miles for the sky team baggage bonus.......but remember, this is china, and what rules apply this morning are often changed this afternoon, by another person...........good luck............
