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 | 33h 03m | 33h 28m |
| Narrowbody jet (A320, 737) | 780 km/h | 23h 18m | 23h 43m |
| Widebody jet (777, 787, A350) | 900 km/h | 20h 12m | 20h 37m |
| Private jet (Gulfstream) | 850 km/h | 21h 23m | 21h 48m |
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 Lisbon to Sydney (Mascot)?
A non-stop flight from Lisbon (LIS) to Sydney (Mascot) (SYD) takes about 23h 00m. The great-circle distance is 18,176 km (11,294 miles, 9,814 nautical miles), flying east on an initial bearing of 79°.
How far is Lisbon from Sydney (Mascot)?
18,176 kilometres in a straight line over the earth's surface — 11,294 miles or 9,814 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 LIS and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 18,176 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 23h 00m 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.
