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 | 23h 22m | 23h 47m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 28m | 16h 53m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 16m | 14h 42m |
| Private jet (Gulfstream) | 850 km/h | 15h 07m | 15h 32m |
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 Hanoi (Soc Son) to Chicago?
A non-stop flight from Hanoi (Soc Son) (HAN) to Chicago (ORD) takes about 16h 23m. The great-circle distance is 12,847 km (7,983 miles, 6,937 nautical miles), flying north on an initial bearing of 11°.
How far is Hanoi (Soc Son) from Chicago?
12,847 kilometres in a straight line over the earth's surface — 7,983 miles or 6,937 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 HAN and ORD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,847 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 16h 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.
