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 18m | 31h 43m |
| Narrowbody jet (A320, 737) | 780 km/h | 22h 04m | 22h 29m |
| Widebody jet (777, 787, A350) | 900 km/h | 19h 08m | 19h 33m |
| Private jet (Gulfstream) | 850 km/h | 20h 15m | 20h 40m |
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 Dublin to Sydney (Mascot)?
A non-stop flight from Dublin (DUB) to Sydney (Mascot) (SYD) takes about 21h 48m. The great-circle distance is 17,214 km (10,696 miles, 9,295 nautical miles), flying north-east on an initial bearing of 48°.
How far is Dublin from Sydney (Mascot)?
17,214 kilometres in a straight line over the earth's surface — 10,696 miles or 9,295 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 DUB and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 17,214 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 48m 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.
