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 31m | 17h 56m |
| Narrowbody jet (A320, 737) | 780 km/h | 12h 21m | 12h 46m |
| Widebody jet (777, 787, A350) | 900 km/h | 10h 42m | 11h 07m |
| Private jet (Gulfstream) | 850 km/h | 11h 20m | 11h 45m |
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 Hong Kong?
A non-stop flight from London (LHR) to Hong Kong (HKG) takes about 12h 23m. The great-circle distance is 9,630 km (5,984 miles, 5,200 nautical miles), flying north-east on an initial bearing of 58°.
How far is London from Hong Kong?
9,630 kilometres in a straight line over the earth's surface — 5,984 miles or 5,200 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 HKG?
This page calculates the direct-line time and distance; it does not track airline schedules. At 9,630 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 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.
