New York to Bangkok
17h 43mgate to gate
The flight from John F. Kennedy International Airport (JFK) to Don Mueang International Airport (DMK) covers 13,922 km (8,650 miles) and takes approximately 17h 43m gate to gate for a typical jet.
The route heads north on an initial great-circle bearing of 7°, passing near 75.7° N, 81.6° 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: 13,922 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 17h 18m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 17h 43m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
13,922 km / 805 km/h = 17h 18m airborne
+ 25 min ground = 17h 43m 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 | 25h 19m | 25h 44m |
| Narrowbody jet (A320, 737) | 780 km/h | 17h 51m | 18h 16m |
| Widebody jet (777, 787, A350) | 900 km/h | 15h 28m | 15h 53m |
| Private jet (Gulfstream) | 850 km/h | 16h 23m | 16h 48m |
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 Bangkok?
A non-stop flight from New York (JFK) to Bangkok (DMK) takes about 17h 43m. The great-circle distance is 13,922 km (8,650 miles, 7,517 nautical miles), flying north on an initial bearing of 7°.
How far is New York from Bangkok?
13,922 kilometres in a straight line over the earth's surface — 8,650 miles or 7,517 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 DMK?
This page calculates the direct-line time and distance; it does not track airline schedules. At 13,922 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 17h 43m 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.
