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 17m | 23h 42m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 25m | 16h 50m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 14m | 14h 39m |
| Private jet (Gulfstream) | 850 km/h | 15h 04m | 15h 29m |
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 Boston to Hong Kong?
A non-stop flight from Boston (BOS) to Hong Kong (HKG) takes about 16h 20m. The great-circle distance is 12,806 km (7,957 miles, 6,915 nautical miles), flying north on an initial bearing of 355°.
How far is Boston from Hong Kong?
12,806 kilometres in a straight line over the earth's surface — 7,957 miles or 6,915 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 BOS and HKG?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,806 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 20m 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.
