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 | 22h 22m | 22h 47m |
| Narrowbody jet (A320, 737) | 780 km/h | 15h 46m | 16h 11m |
| Widebody jet (777, 787, A350) | 900 km/h | 13h 40m | 14h 05m |
| Private jet (Gulfstream) | 850 km/h | 14h 28m | 14h 53m |
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 Los Angeles to Hanoi (Soc Son)?
A non-stop flight from Los Angeles (LAX) to Hanoi (Soc Son) (HAN) takes about 15h 42m. The great-circle distance is 12,300 km (7,643 miles, 6,642 nautical miles), flying north-west on an initial bearing of 316°.
How far is Los Angeles from Hanoi (Soc Son)?
12,300 kilometres in a straight line over the earth's surface — 7,643 miles or 6,642 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 LAX and HAN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,300 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 15h 42m 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.
