Seoul to Kochi
7h 40mgate to gate
The flight from Incheon International Airport (ICN) to Cochin International Airport (COK) covers 5,837 km (3,627 miles) and takes approximately 7h 40m gate to gate for a typical jet.
The route heads west on an initial great-circle bearing of 252°, passing near 25.9° N, 98.6° E 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: 5,837 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 7h 15m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 7h 40m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
5,837 km / 805 km/h = 7h 15m airborne
+ 25 min ground = 7h 40m 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 | 10h 37m | 11h 02m |
| Narrowbody jet (A320, 737) | 780 km/h | 7h 29m | 7h 54m |
| Widebody jet (777, 787, A350) | 900 km/h | 6h 29m | 6h 54m |
| Private jet (Gulfstream) | 850 km/h | 6h 52m | 7h 17m |
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 Seoul to Kochi?
A non-stop flight from Seoul (ICN) to Kochi (COK) takes about 7h 40m. The great-circle distance is 5,837 km (3,627 miles, 3,152 nautical miles), flying west on an initial bearing of 252°.
How far is Seoul from Kochi?
5,837 kilometres in a straight line over the earth's surface — 3,627 miles or 3,152 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 COK?
This page calculates the direct-line time and distance; it does not track airline schedules. At 5,837 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
What should I expect on a 7h 40m 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.
