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 50m | 23h 15m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 06m | 16h 31m |
| Widebody jet (777, 787, A350) | 900 km/h | 13h 57m | 14h 22m |
| Private jet (Gulfstream) | 850 km/h | 14h 47m | 15h 12m |
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 Phoenix?
A non-stop flight from Sydney (Mascot) (SYD) to Phoenix (PHX) takes about 16h 01m. The great-circle distance is 12,559 km (7,804 miles, 6,781 nautical miles), flying north-east on an initial bearing of 64°.
How far is Sydney (Mascot) from Phoenix?
12,559 kilometres in a straight line over the earth's surface — 7,804 miles or 6,781 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 PHX?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,559 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 16h 01m 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.
