The route
The great-circle path — the shortest line between the two airports across the curve of the earth. On a flat map it 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 02m | 16h 28m |
| Narrowbody jet (A320, 737) | 780 km/h | 11h 19m | 11h 44m |
| Widebody jet (777, 787, A350) | 900 km/h | 9h 48m | 10h 13m |
| Private jet (Gulfstream) | 850 km/h | 10h 23m | 10h 48m |
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
How long is the flight from Reykjavík to Narita?
A non-stop flight from Reykjavík (KEF) to Narita (NRT) takes about 11h 23m. The great-circle distance is 8,822 km (5,482 miles, 4,764 nautical miles), flying north on an initial bearing of 14°.
How far is Reykjavík from Narita?
8,822 kilometres in a straight line over the earth's surface — 5,482 miles or 4,764 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 KEF and NRT?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,822 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 23m 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.
