New York to Johannesburg
16h 22mgate to gate
The flight from John F. Kennedy International Airport (JFK) to O.R. Tambo International Airport (JNB) covers 12,831 km (7,973 miles) and takes approximately 16h 22m gate to gate for a typical jet.
The route heads east on an initial great-circle bearing of 104°, passing near 11.4° N, 16.9° W 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: 12,831 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 15h 56m.
- 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 22m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
12,831 km / 805 km/h = 15h 56m airborne
+ 25 min ground = 16h 22m 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 20m | 23h 45m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 27m | 16h 52m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 15m | 14h 41m |
| Private jet (Gulfstream) | 850 km/h | 15h 06m | 15h 31m |
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 Johannesburg?
A non-stop flight from New York (JFK) to Johannesburg (JNB) takes about 16h 22m. The great-circle distance is 12,831 km (7,973 miles, 6,928 nautical miles), flying east on an initial bearing of 104°.
How far is New York from Johannesburg?
12,831 kilometres in a straight line over the earth's surface — 7,973 miles or 6,928 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 JNB?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,831 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 22m 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.
