Questions
How long is the flight from Sydney (Mascot) to Dallas-Fort Worth?
A non-stop flight from Sydney (Mascot) (SYD) to Dallas-Fort Worth (DFW) takes about 17h 34m. The great-circle distance is 13,808 km (8,580 miles, 7,456 nautical miles), flying east on an initial bearing of 70°.
How far is Sydney (Mascot) from Dallas-Fort Worth?
13,808 kilometres in a straight line over the earth's surface — 8,580 miles or 7,456 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 DFW?
This page calculates the direct-line time and distance; it does not track airline schedules. At 13,808 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 34m 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.
