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 | 27h 19m | 27h 44m |
| Narrowbody jet (A320, 737) | 780 km/h | 19h 16m | 19h 41m |
| Widebody jet (777, 787, A350) | 900 km/h | 16h 41m | 17h 07m |
| Private jet (Gulfstream) | 850 km/h | 17h 40m | 18h 06m |
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 Miami to Sydney (Mascot)?
A non-stop flight from Miami (MIA) to Sydney (Mascot) (SYD) takes about 19h 05m. The great-circle distance is 15,022 km (9,334 miles, 8,111 nautical miles), flying south-west on an initial bearing of 247°.
How far is Miami from Sydney (Mascot)?
15,022 kilometres in a straight line over the earth's surface — 9,334 miles or 8,111 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 MIA and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,022 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 19h 05m 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.
