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 | 24h 48m | 25h 13m |
| Narrowbody jet (A320, 737) | 780 km/h | 17h 29m | 17h 54m |
| Widebody jet (777, 787, A350) | 900 km/h | 15h 09m | 15h 35m |
| Private jet (Gulfstream) | 850 km/h | 16h 03m | 16h 28m |
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 Austin to Sydney (Mascot)?
A non-stop flight from Austin (AUS) to Sydney (Mascot) (SYD) takes about 17h 22m. The great-circle distance is 13,640 km (8,475 miles, 7,365 nautical miles), flying south-west on an initial bearing of 247°.
How far is Austin from Sydney (Mascot)?
13,640 kilometres in a straight line over the earth's surface — 8,475 miles or 7,365 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 AUS and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 13,640 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 17h 22m 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.
