Seoul to Fort Lauderdale
15h 51mgate to gate
The flight from Incheon International Airport (ICN) to Fort Lauderdale Hollywood International Airport (FLL) covers 12,423 km (7,719 miles) and takes approximately 15h 51m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 26°, passing near 69.0° N, 142.2° 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: 12,423 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 15h 26m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 15h 51m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
12,423 km / 805 km/h = 15h 26m airborne
+ 25 min ground = 15h 51m 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 | 22h 35m | 23h 00m |
| Narrowbody jet (A320, 737) | 780 km/h | 15h 56m | 16h 21m |
| Widebody jet (777, 787, A350) | 900 km/h | 13h 48m | 14h 13m |
| Private jet (Gulfstream) | 850 km/h | 14h 37m | 15h 02m |
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 Fort Lauderdale?
A non-stop flight from Seoul (ICN) to Fort Lauderdale (FLL) takes about 15h 51m. The great-circle distance is 12,423 km (7,719 miles, 6,708 nautical miles), flying north-east on an initial bearing of 26°.
How far is Seoul from Fort Lauderdale?
12,423 kilometres in a straight line over the earth's surface — 7,719 miles or 6,708 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 FLL?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,423 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 15h 51m 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.
