New York to Seoul: distance, flight time and the route it really takes

John F. Kennedy to Incheon is 11,089 km of great circle — 6,890 mi — and an estimated 14h 17m in the air. It crosses from North America to Asia.

What the aircraft actually flies over

From New York the path crosses the United States, then Canada, then 1,497 km of open water, then Canada, then 2,939 km of open water, then Russia, then China, then North Korea.

The great circle reaches 77.8°N, inside the Arctic circle — which is why the route looks like a detour over the top of the world on a flat map, and like the obvious line on a globe.

Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 13,796 km. That is 2,707 km further, about 24% more, and roughly 3h 22m of extra flying.

How these numbers are worked out

The distance is the great circle between the two airports’ real coordinates — the shortest path over a sphere, and the measure airlines and loyalty programmes use. It is computed, not looked up from a table of published routes.

The time is an estimate derived from that distance, using the same arithmetic Orbit uses when you log a flight without timestamps: a typical airliner block speed of 500 mph plus thirty minutes for taxi, climb and descent. Real schedules run longer or shorter depending on winds, air traffic control routing and how far the gate is from the runway. Aircraft also do not fly perfect great circles — jet streams, airspace closures and ETOPS limits all bend the path, usually by a few percent.
