Kunming to London
11h 15mgate to gate
The flight from Kunming Changshui International Airport (KMG) to London Heathrow Airport (LHR) covers 8,716 km (5,416 miles) and takes approximately 11h 15m gate to gate for a typical jet.
The route heads north-west on an initial great-circle bearing of 322°, passing near 51.1° N, 64.4° 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: 8,716 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 10h 50m.
- 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 15m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
8,716 km / 805 km/h = 10h 50m airborne
+ 25 min ground = 11h 15m 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 | 15h 51m | 16h 16m |
| Narrowbody jet (A320, 737) | 780 km/h | 11h 10m | 11h 36m |
| Widebody jet (777, 787, A350) | 900 km/h | 9h 41m | 10h 06m |
| Private jet (Gulfstream) | 850 km/h | 10h 15m | 10h 40m |
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 Kunming to London?
A non-stop flight from Kunming (KMG) to London (LHR) takes about 11h 15m. The great-circle distance is 8,716 km (5,416 miles, 4,706 nautical miles), flying north-west on an initial bearing of 322°.
How far is Kunming from London?
8,716 kilometres in a straight line over the earth's surface — 5,416 miles or 4,706 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 KMG and LHR?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,716 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 15m 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.
