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 | 1h 49m | 2h 14m |
| Narrowbody jet (A320, 737) | 780 km/h | 1h 17m | 1h 42m |
| Widebody jet (777, 787, A350) | 900 km/h | 1h 06m | 1h 32m |
| Private jet (Gulfstream) | 850 km/h | 1h 10m | 1h 36m |
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.
