Hong Kong to Boston
16h 20mgate to gate
The flight from Hong Kong International Airport (HKG) to Boston Logan International Airport (BOS) covers 12,806 km (7,957 miles) and takes approximately 16h 20m gate to gate for a typical jet.
The route heads north on an initial great-circle bearing of 4°, passing near 79.3° N, 132.5° E at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 12,806 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 15h 54m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 16h 20m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
12,806 km / 805 km/h = 15h 54m airborne
+ 25 min ground = 16h 20m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path 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 this plate answers
How long is the flight from Hong Kong to Boston?
A non-stop flight from Hong Kong (HKG) to Boston (BOS) 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 4°.
How far is Hong Kong from Boston?
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 HKG and BOS?
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.
