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 | 18h 35m | 19h 00m |
| Narrowbody jet (A320, 737) | 780 km/h | 13h 06m | 13h 31m |
| Widebody jet (777, 787, A350) | 900 km/h | 11h 21m | 11h 46m |
| Private jet (Gulfstream) | 850 km/h | 12h 01m | 12h 27m |
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 Ho Chi Minh City?
A non-stop flight from London (LHR) to Ho Chi Minh City (SGN) takes about 13h 07m. The great-circle distance is 10,219 km (6,350 miles, 5,518 nautical miles), flying east on an initial bearing of 70°.
How far is London from Ho Chi Minh City?
10,219 kilometres in a straight line over the earth's surface — 6,350 miles or 5,518 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 SGN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 10,219 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 13h 07m 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.
