Sydney (Mascot) to Bologna
20h 48mgate to gate
The flight from Sydney Kingsford Smith International Airport (SYD) to Bologna Guglielmo Marconi Airport (BLQ) covers 16,407 km (10,195 miles) and takes approximately 20h 48m gate to gate for a typical jet.
The route heads north-west on an initial great-circle bearing of 301°, passing near 14.8° N, 92.9° 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: 16,407 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 20h 23m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 20h 48m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
16,407 km / 805 km/h = 20h 23m airborne
+ 25 min ground = 20h 48m 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 | 29h 50m | 30h 15m |
| Narrowbody jet (A320, 737) | 780 km/h | 21h 02m | 21h 27m |
| Widebody jet (777, 787, A350) | 900 km/h | 18h 14m | 18h 39m |
| Private jet (Gulfstream) | 850 km/h | 19h 18m | 19h 43m |
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 Sydney (Mascot) to Bologna?
A non-stop flight from Sydney (Mascot) (SYD) to Bologna (BLQ) takes about 20h 48m. The great-circle distance is 16,407 km (10,195 miles, 8,859 nautical miles), flying north-west on an initial bearing of 301°.
How far is Sydney (Mascot) from Bologna?
16,407 kilometres in a straight line over the earth's surface — 10,195 miles or 8,859 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 BLQ?
This page calculates the direct-line time and distance; it does not track airline schedules. At 16,407 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 48m 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.
