Seoul to Wellington

12h 54mgate to gate

The flight from Incheon International Airport (ICN) to Wellington International Airport (WLG) covers 10,044 km (6,241 miles) and takes approximately 12h 54m gate to gate for a typical jet.

The route heads south-east on an initial great-circle bearing of 146°, passing near 2.1° S, 149.9° E at its midpoint.

How this is worked out

  1. Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
  2. Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 10,044 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 12h 29m.
  4. Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 12h 54m gate to gate.
  5. Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
10,044 km / 805 km/h = 12h 29m airborne
            + 25 min ground = 12h 54m 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.

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 Wellington?

A non-stop flight from Seoul (ICN) to Wellington (WLG) takes about 12h 54m. The great-circle distance is 10,044 km (6,241 miles, 5,423 nautical miles), flying south-east on an initial bearing of 146°.

How far is Seoul from Wellington?

10,044 kilometres in a straight line over the earth's surface — 6,241 miles or 5,423 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 WLG?

This page calculates the direct-line time and distance; it does not track airline schedules. At 10,044 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 12h 54m 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.

Airport coordinates from OurAirports (public domain). Distance is a great-circle calculation; flight time uses the model described on the method page. Flight times are great-circle estimates for planning only — always check the airline's published schedule.
