Seoul to Dublin
11h 31mgate to gate
The flight from Incheon International Airport (ICN) to Dublin Airport (DUB) covers 8,934 km (5,551 miles) and takes approximately 11h 31m gate to gate for a typical jet.
The route heads north-west on an initial great-circle bearing of 334°, passing near 67.5° N, 78.1° 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: 8,934 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 11h 06m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 11h 31m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
8,934 km / 805 km/h = 11h 06m airborne
+ 25 min ground = 11h 31m 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 | 16h 15m | 16h 40m |
| Narrowbody jet (A320, 737) | 780 km/h | 11h 27m | 11h 52m |
| Widebody jet (777, 787, A350) | 900 km/h | 9h 56m | 10h 21m |
| Private jet (Gulfstream) | 850 km/h | 10h 31m | 10h 56m |
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 Dublin?
A non-stop flight from Seoul (ICN) to Dublin (DUB) takes about 11h 31m. The great-circle distance is 8,934 km (5,551 miles, 4,824 nautical miles), flying north-west on an initial bearing of 334°.
How far is Seoul from Dublin?
8,934 kilometres in a straight line over the earth's surface — 5,551 miles or 4,824 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 DUB?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,934 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 11h 31m 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.
