moondog, thanks for your calculations! This is very helpful.
Are their awards strictly distance based? i.e. could I use this for HKG-TPE or HKG-BKK, even though neither are fully in China? If so, this could be very useful as a connecting flight after getting into HKG.
Also, are mileage awards based upon actual distance flown or the distance between Origin and Destination?
Based upon what I'm hearing so far, it sounds like crediting to CZ might not be such a bad idea. Thanks!
