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 | 31h 08m | 31h 33m |
| Narrowbody jet (A320, 737) | 780 km/h | 21h 57m | 22h 22m |
| Widebody jet (777, 787, A350) | 900 km/h | 19h 02m | 19h 27m |
| Private jet (Gulfstream) | 850 km/h | 20h 09m | 20h 34m |
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 New York to Adelaide?
A non-stop flight from New York (JFK) to Adelaide (ADL) takes about 21h 41m. The great-circle distance is 17,123 km (10,640 miles, 9,246 nautical miles), flying west on an initial bearing of 272°.
How far is New York from Adelaide?
17,123 kilometres in a straight line over the earth's surface — 10,640 miles or 9,246 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 ADL?
This page calculates the direct-line time and distance; it does not track airline schedules. At 17,123 km the route is at the extreme end of what any airliner can fly non-stop, so a connection is likely. Check an airline or booking site for what is actually scheduled.
What should I expect on a 21h 41m 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.
