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 | 15h 56m | 16h 21m |

Questions
How long is the flight from Sydney (Mascot) to Colombo?
A non-stop flight from Sydney (Mascot) (SYD) to Colombo (CMB) takes about 11h 18m. The great-circle distance is 8,763 km (5,445 miles, 4,731 nautical miles), flying west on an initial bearing of 287°.
How far is Sydney (Mascot) from Colombo?
8,763 kilometres in a straight line over the earth's surface — 5,445 miles or 4,731 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 CMB?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,763 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
What should I expect on a 11h 18m 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.
