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 | 17h 26m | 17h 52m |
| Narrowbody jet (A320, 737) | 780 km/h | 12h 18m | 12h 43m |
| Widebody jet (777, 787, A350) | 900 km/h | 10h 39m | 11h 05m |
| Private jet (Gulfstream) | 850 km/h | 11h 17m | 11h 42m |
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 London to Narita?
A non-stop flight from London (LHR) to Narita (NRT) takes about 12h 20m. The great-circle distance is 9,591 km (5,960 miles, 5,179 nautical miles), flying north-east on an initial bearing of 31°.
How far is London from Narita?
9,591 kilometres in a straight line over the earth's surface — 5,960 miles or 5,179 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 LHR and NRT?
This page calculates the direct-line time and distance; it does not track airline schedules. At 9,591 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 12h 20m 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.
