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 | 32h 51m | 33h 16m |
| Narrowbody jet (A320, 737) | 780 km/h | 23h 10m | 23h 35m |
| Widebody jet (777, 787, A350) | 900 km/h | 20h 05m | 20h 30m |
| Private jet (Gulfstream) | 850 km/h | 21h 16m | 21h 41m |
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 Sydney (Mascot) to Porto?
A non-stop flight from Sydney (Mascot) (SYD) to Porto (OPO) takes about 22h 52m. The great-circle distance is 18,070 km (11,228 miles, 9,757 nautical miles), flying north-west on an initial bearing of 301°.
How far is Sydney (Mascot) from Porto?
18,070 kilometres in a straight line over the earth's surface — 11,228 miles or 9,757 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 SYD and OPO?
This page calculates the direct-line time and distance; it does not track airline schedules. At 18,070 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 22h 52m 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.
