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 | 28h 40m | 29h 06m |
| Narrowbody jet (A320, 737) | 780 km/h | 20h 13m | 20h 38m |
| Widebody jet (777, 787, A350) | 900 km/h | 17h 31m | 17h 57m |
| Private jet (Gulfstream) | 850 km/h | 18h 33m | 18h 58m |
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 Budapest to Sydney (Mascot)?
A non-stop flight from Budapest (BUD) to Sydney (Mascot) (SYD) takes about 20h 01m. The great-circle distance is 15,770 km (9,799 miles, 8,515 nautical miles), flying east on an initial bearing of 87°.
How far is Budapest from Sydney (Mascot)?
15,770 kilometres in a straight line over the earth's surface — 9,799 miles or 8,515 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 BUD and SYD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,770 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 01m 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.
