Disappointed to see this route go, however every time I would visit Shaanxi or Xian we would go to Shanghai first to visit with our China HQ first, making the non stop flight completely pointless for me. Also that whole area is a big oil / petrochemical area, quite possible the slow down in global commodities negatively effected this route. The good news is it is still really easy to get to Xian from any of the major Chinese cities.
