Istanbul to Sapporo
11h 00mgate to gate
The flight from İstanbul Airport (IST) to New Chitose Airport (CTS) covers 8,511 km (5,288 miles) and takes approximately 11h 00m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 44°, passing near 58.5° N, 84.2° 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: 8,511 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 10h 34m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 11h 00m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
8,511 km / 805 km/h = 10h 34m airborne
+ 25 min ground = 11h 00m 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 | 15h 28m | 15h 54m |
| Narrowbody jet (A320, 737) | 780 km/h | 10h 55m | 11h 20m |
| Widebody jet (777, 787, A350) | 900 km/h | 9h 27m | 9h 53m |
| Private jet (Gulfstream) | 850 km/h | 10h 01m | 10h 26m |
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 Istanbul to Sapporo?
A non-stop flight from Istanbul (IST) to Sapporo (CTS) takes about 11h 00m. The great-circle distance is 8,511 km (5,288 miles, 4,595 nautical miles), flying north-east on an initial bearing of 44°.
How far is Istanbul from Sapporo?
8,511 kilometres in a straight line over the earth's surface — 5,288 miles or 4,595 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 CTS?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,511 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
What should I expect on a 11h 00m 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.
