Okay...I think I can reveal it now...
1st destination is:Shanghai,China
Well actually, Shanghai is the only destination that makes sense from flight stats.....there are not any other cities that fit the flight profiles except either Hong Kong or Macau.....and they might go there......but I would think after they go someplace else in China first......
