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 48m | 31h 14m |
| Narrowbody jet (A320, 737) | 780 km/h | 21h 43m | 22h 09m |
| Widebody jet (777, 787, A350) | 900 km/h | 18h 50m | 19h 15m |
| Private jet (Gulfstream) | 850 km/h | 19h 56m | 20h 21m |
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 Paris (Roissy-en-France, Val-d'Oise) to Sydney (Mascot)?
A non-stop flight from Paris (Roissy-en-France, Val-d'Oise) (CDG) to Sydney (Mascot) (SYD) takes about 21h 28m. The great-circle distance is 16,944 km (10,529 miles, 9,149 nautical miles), flying east on an initial bearing of 69°.
How far is Paris (Roissy-en-France, Val-d'Oise) from Sydney (Mascot)?
16,944 kilometres in a straight line over the earth's surface — 10,529 miles or 9,149 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 CDG and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 16,944 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 28m 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.
