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 | 22h 37m | 23h 02m |
| Narrowbody jet (A320, 737) | 780 km/h | 15h 57m | 16h 22m |
| Widebody jet (777, 787, A350) | 900 km/h | 13h 49m | 14h 14m |
| Private jet (Gulfstream) | 850 km/h | 14h 38m | 15h 03m |
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 Las Vegas to Sydney (Mascot)?
A non-stop flight from Las Vegas (LAS) to Sydney (Mascot) (SYD) takes about 15h 52m. The great-circle distance is 12,435 km (7,727 miles, 6,714 nautical miles), flying south-west on an initial bearing of 243°.
How far is Las Vegas from Sydney (Mascot)?
12,435 kilometres in a straight line over the earth's surface — 7,727 miles or 6,714 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 LAS and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,435 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 15h 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.
