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 | 18h 13m | 18h 38m |
| Narrowbody jet (A320, 737) | 780 km/h | 12h 51m | 13h 16m |
| Widebody jet (777, 787, A350) | 900 km/h | 11h 08m | 11h 33m |
| Private jet (Gulfstream) | 850 km/h | 11h 47m | 12h 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 Lucknow to Sydney (Mascot)?
A non-stop flight from Lucknow (LKO) to Sydney (Mascot) (SYD) takes about 12h 52m. The great-circle distance is 10,018 km (6,225 miles, 5,409 nautical miles), flying south-east on an initial bearing of 129°.
How far is Lucknow from Sydney (Mascot)?
10,018 kilometres in a straight line over the earth's surface — 6,225 miles or 5,409 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 LKO and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 10,018 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 12h 52m 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.
