How far is it from Beijing to Washington and new york (mileage) and how far is it by air (flying time)?

It is 7400 miles (1 1900 km) from Beijing to new york. I don't know the flight time, usually 13 hours, but it depends on the airline. Airlines in the United States are generally faster (12 and 13 hours), while those in China are slower (14 and 15 hours).

If you have a visa, it is convenient to fly to Seoul. The price is not clear, but it will be close soon.

Washington is farther than new york, but it is only+1 hour at most.
