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.

Questions
How long is the flight from Sydney (Mascot) to Detroit?
A non-stop flight from Sydney (Mascot) (SYD) to Detroit (DTW) takes about 19h 21m. The great-circle distance is 15,237 km (9,468 miles, 8,227 nautical miles), flying north-east on an initial bearing of 62°.
How far is Sydney (Mascot) from Detroit?
15,237 kilometres in a straight line over the earth's surface — 9,468 miles or 8,227 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 DTW?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,237 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 21m 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.
