BTW, for silliness sakes, I tried to trace route the flight back to its origin and found that there was another UPS flight number before UPS 91 took over the cargo. From what i saw, there's a set of flight numbers for UPS 173/174 that travel between ZHCC and RKSI nearly daily around the time the departure and arrival timestamps occured, but it's hard to get a full confirmation of it...I'm thinking I'm gonna try and see tonight if it lights up on flightaware around the intended departure time.
