How long does it take to fly from Beijing to Pyeongchang, South Korea?

It takes about three hours. The straight-line distance from Beijing to Pyeongchang is about 960 kilometers, and the average speed of the plane is about 800 kilometers per hour, so theoretically the flight time should be about 1 hour for 20 minutes. But in fact, the route of the plane is not a straight line, and it needs to be adjusted according to air traffic control, meteorological conditions, wind direction, connecting time and other factors, so the actual flight time will increase.
