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 | 15h 47m | 16h 12m |
| Narrowbody jet (A320, 737) | 780 km/h | 11h 08m | 11h 33m |
| Widebody jet (777, 787, A350) | 900 km/h | 9h 39m | 10h 04m |
| Private jet (Gulfstream) | 850 km/h | 10h 13m | 10h 38m |
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 Singapore?
A non-stop flight from Istanbul (IST) to Singapore (SIN) takes about 11h 12m. The great-circle distance is 8,681 km (5,394 miles, 4,687 nautical miles), flying east on an initial bearing of 99°.
How far is Istanbul from Singapore?
8,681 kilometres in a straight line over the earth's surface — 5,394 miles or 4,687 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 SIN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,681 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 12m 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.
