The route
The great-circle path — the shortest line between the two airports across the curve of the earth. On a flat map it looks bent; on a globe it is straight.
Flight time at different cruise speeds
Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 20h 08m | 20h 33m |
| Narrowbody jet (A320, 737) | 780 km/h | 14h 12m | 14h 37m |
| Widebody jet (777, 787, A350) | 900 km/h | 12h 18m | 12h 43m |
| Private jet (Gulfstream) | 850 km/h | 13h 02m | 13h 27m |
Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions
How long is the flight from Seoul to Newark?
A non-stop flight from Seoul (ICN) to Newark (EWR) takes about 14h 11m. The great-circle distance is 11,074 km (6,881 miles, 5,980 nautical miles), flying north on an initial bearing of 16°.
How far is Seoul from Newark?
11,074 kilometres in a straight line over the earth's surface — 6,881 miles or 5,980 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.
Is there a non-stop flight between ICN and EWR?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,074 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 14h 11m flight?
Anything past six hours is a long-haul flight: expect at least one meal service, a significant time-zone shift, and enough sitting that circulation and hydration start to matter. Cabin altitude, dry air and disrupted sleep do more damage to a training routine than the flight itself.
