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 | 28h 46m | 29h 11m |
| Narrowbody jet (A320, 737) | 780 km/h | 20h 17m | 20h 42m |
| Widebody jet (777, 787, A350) | 900 km/h | 17h 35m | 18h 00m |
| Private jet (Gulfstream) | 850 km/h | 18h 37m | 19h 02m |
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 Singapore to Austin?
A non-stop flight from Singapore (SIN) to Austin (AUS) takes about 20h 05m. The great-circle distance is 15,823 km (9,832 miles, 8,544 nautical miles), flying north-east on an initial bearing of 31°.
How far is Singapore from Austin?
15,823 kilometres in a straight line over the earth's surface — 9,832 miles or 8,544 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 SIN and AUS?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,823 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 20h 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.
