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 | 30h 30m | 30h 56m |
| Narrowbody jet (A320, 737) | 780 km/h | 21h 31m | 21h 56m |
| Widebody jet (777, 787, A350) | 900 km/h | 18h 39m | 19h 04m |
| Private jet (Gulfstream) | 850 km/h | 19h 44m | 20h 10m |
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 Geneva to Sydney (Mascot)?
A non-stop flight from Geneva (GVA) to Sydney (Mascot) (SYD) takes about 21h 16m. The great-circle distance is 16,778 km (10,426 miles, 9,060 nautical miles), flying east on an initial bearing of 78°.
How far is Geneva from Sydney (Mascot)?
16,778 kilometres in a straight line over the earth's surface — 10,426 miles or 9,060 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 GVA and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 16,778 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 16m 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.
