New York to Hangzhou
15h 20mgate to gate
The flight from John F. Kennedy International Airport (JFK) to Hangzhou Xiaoshan International Airport (HGH) covers 11,999 km (7,456 miles) and takes approximately 15h 20m gate to gate for a typical jet.
The route heads north on an initial great-circle bearing of 347°, passing near 78.9° N, 175.9° 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: 11,999 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 14h 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: 15h 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.
11,999 km / 805 km/h = 14h 54m airborne
+ 25 min ground = 15h 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 | 21h 49m | 22h 14m |
| Narrowbody jet (A320, 737) | 780 km/h | 15h 23m | 15h 48m |
| Widebody jet (777, 787, A350) | 900 km/h | 13h 20m | 13h 45m |
| Private jet (Gulfstream) | 850 km/h | 14h 07m | 14h 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 this plate answers
How long is the flight from New York to Hangzhou?
A non-stop flight from New York (JFK) to Hangzhou (HGH) takes about 15h 20m. The great-circle distance is 11,999 km (7,456 miles, 6,479 nautical miles), flying north on an initial bearing of 347°.
How far is New York from Hangzhou?
11,999 kilometres in a straight line over the earth's surface — 7,456 miles or 6,479 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 JFK and HGH?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,999 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 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.
