browneyes-we've done JNB, NRT, and DXB from ATL all on 777. Yep, those are LONG flights. DXB might be of interest. China destination may be an issue w/out visa (nonrev is different from rev short stay). HKG from DTW was a delight; but now you have SEA/HKG. Are you just going to do a turn-around? I'm not sure if you can clear all of those airports w/out going to the departure desks. I know you can do it at SIN IF you have enough time.
