What is the direct flight distance from Beijing to Seattle?

The equipment simulated and measured 4690 nautical miles.

At this time, with the help of some positioning simulation systems, the data calculated from the linear distance from Beijing International Airport to Seattle Tacoma International Airport are as follows.

In addition, the distance between Beijing and Seattle is also related to the following factors:

Generally, within the flight distance, many passenger planes will pass through the air or natural disasters will occur in front of the plane during the flight. Therefore, if there is an abnormality in front of the plane when flying in the air passage, the plane will command the plane to fly around in time through its own radar/ground director.

So the direct flight distance from Beijing to Seattle sometimes changes. In addition, the flight needs to arrive at the airport 1 hour in advance, so as not to affect normal travel.
