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 | 31h 01m | 31h 26m |
| Narrowbody jet (A320, 737) | 780 km/h | 21h 52m | 22h 17m |
| Widebody jet (777, 787, A350) | 900 km/h | 18h 57m | 19h 22m |
| Private jet (Gulfstream) | 850 km/h | 20h 04m | 20h 29m |
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 Istanbul to Christchurch?
A non-stop flight from Istanbul (IST) to Christchurch (CHC) takes about 21h 36m. The great-circle distance is 17,055 km (10,598 miles, 9,209 nautical miles), flying east on an initial bearing of 107°.
How far is Istanbul from Christchurch?
17,055 kilometres in a straight line over the earth's surface — 10,598 miles or 9,209 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 IST and CHC?
This page calculates the direct-line time and distance; it does not track airline schedules. At 17,055 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 36m 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.
