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 | 13h 29m | 13h 54m |
| Narrowbody jet (A320, 737) | 780 km/h | 9h 31m | 9h 56m |
| Widebody jet (777, 787, A350) | 900 km/h | 8h 14m | 8h 40m |
| Private jet (Gulfstream) | 850 km/h | 8h 44m | 9h 09m |
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 Istanbul to Hanoi (Soc Son)?
A non-stop flight from Istanbul (IST) to Hanoi (Soc Son) (HAN) takes about 9h 38m. The great-circle distance is 7,417 km (4,609 miles, 4,005 nautical miles), flying east on an initial bearing of 82°.
How far is Istanbul from Hanoi (Soc Son)?
7,417 kilometres in a straight line over the earth's surface — 4,609 miles or 4,005 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 IST and HAN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 7,417 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 9h 38m 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.
