New York to Seoul
14h 10mgate to gate
The flight from LaGuardia Airport (LGA) to Incheon International Airport (ICN) covers 11,072 km (6,880 miles) and takes approximately 14h 10m gate to gate for a typical jet.
The route heads north on an initial great-circle bearing of 344°, passing near 77.7° N, 161.2° W at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 11,072 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 13h 45m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 14h 10m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
11,072 km / 805 km/h = 13h 45m airborne
+ 25 min ground = 14h 10m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path 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 this plate answers
How long is the flight from New York to Seoul?
A non-stop flight from New York (LGA) to Seoul (ICN) takes about 14h 10m. The great-circle distance is 11,072 km (6,880 miles, 5,978 nautical miles), flying north on an initial bearing of 344°.
How far is New York from Seoul?
11,072 kilometres in a straight line over the earth's surface — 6,880 miles or 5,978 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 LGA and ICN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,072 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 10m 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.
