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 | 29h 16m | 29h 42m |
| Narrowbody jet (A320, 737) | 780 km/h | 20h 38m | 21h 04m |
| Widebody jet (777, 787, A350) | 900 km/h | 17h 53m | 18h 19m |
| Private jet (Gulfstream) | 850 km/h | 18h 56m | 19h 22m |
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 Prague to Sydney (Mascot)?
A non-stop flight from Prague (PRG) to Sydney (Mascot) (SYD) takes about 20h 25m. The great-circle distance is 16,100 km (10,004 miles, 8,693 nautical miles), flying east on an initial bearing of 79°.
How far is Prague from Sydney (Mascot)?
16,100 kilometres in a straight line over the earth's surface — 10,004 miles or 8,693 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 PRG and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 16,100 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 20h 25m 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.
