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 | 14h 09m | 14h 34m |
| Narrowbody jet (A320, 737) | 780 km/h | 9h 59m | 10h 24m |
| Widebody jet (777, 787, A350) | 900 km/h | 8h 39m | 9h 04m |
| Private jet (Gulfstream) | 850 km/h | 9h 09m | 9h 35m |
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 Osaka to Sydney (Mascot)?
A non-stop flight from Osaka (KIX) to Sydney (Mascot) (SYD) takes about 10h 05m. The great-circle distance is 7,782 km (4,835 miles, 4,202 nautical miles), flying south on an initial bearing of 166°.
How far is Osaka from Sydney (Mascot)?
7,782 kilometres in a straight line over the earth's surface — 4,835 miles or 4,202 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 KIX and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 7,782 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
What should I expect on a 10h 05m 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.
