Spata-Artemida to Sydney (Mascot)
19h 26mgate to gate
The flight from Athens Eleftherios Venizelos International Airport (ATH) to Sydney Kingsford Smith International Airport (SYD) covers 15,307 km (9,511 miles) and takes approximately 19h 26m gate to gate for a typical jet.
The route heads east on an initial great-circle bearing of 101°, passing near 4.5° N, 90.5° E at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 15,307 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 19h 01m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 19h 26m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
15,307 km / 805 km/h = 19h 01m airborne
+ 25 min ground = 19h 26m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path 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 | 27h 50m | 28h 15m |
| Narrowbody jet (A320, 737) | 780 km/h | 19h 37m | 20h 03m |
| Widebody jet (777, 787, A350) | 900 km/h | 17h 00m | 17h 26m |
| Private jet (Gulfstream) | 850 km/h | 18h 01m | 18h 26m |
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 this plate answers
How long is the flight from Spata-Artemida to Sydney (Mascot)?
A non-stop flight from Spata-Artemida (ATH) to Sydney (Mascot) (SYD) takes about 19h 26m. The great-circle distance is 15,307 km (9,511 miles, 8,265 nautical miles), flying east on an initial bearing of 101°.
How far is Spata-Artemida from Sydney (Mascot)?
15,307 kilometres in a straight line over the earth's surface — 9,511 miles or 8,265 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 ATH and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,307 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 26m 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.
