Barcelona to Sydney (Mascot)
21h 46mgate to gate
The flight from Josep Tarradellas Barcelona-El Prat Airport (BCN) to Sydney Kingsford Smith International Airport (SYD) covers 17,190 km (10,682 miles) and takes approximately 21h 46m gate to gate for a typical jet.
The route heads east on an initial great-circle bearing of 83°, passing near 13.4° N, 86.8° 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: 17,190 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 21h 21m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 21h 46m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
17,190 km / 805 km/h = 21h 21m airborne
+ 25 min ground = 21h 46m 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 | 31h 15m | 31h 41m |
| Narrowbody jet (A320, 737) | 780 km/h | 22h 02m | 22h 28m |
| Widebody jet (777, 787, A350) | 900 km/h | 19h 06m | 19h 31m |
| Private jet (Gulfstream) | 850 km/h | 20h 13m | 20h 39m |
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 Barcelona to Sydney (Mascot)?
A non-stop flight from Barcelona (BCN) to Sydney (Mascot) (SYD) takes about 21h 46m. The great-circle distance is 17,190 km (10,682 miles, 9,282 nautical miles), flying east on an initial bearing of 83°.
How far is Barcelona from Sydney (Mascot)?
17,190 kilometres in a straight line over the earth's surface — 10,682 miles or 9,282 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 BCN and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 17,190 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 21h 46m 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.
