How the Sulaymaniyah to Istanbul route actually runs
Pro Flight Search records official board updates for nonstop ISU to IST flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

ISU to IST questions
Is ISU–IST running on time right now?
Some delays possible. The arrival side at IST is the weaker end, route health score 60/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ISU to IST?
Great-circle distance is 1,573 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 141–165 min gate-to-gate on this route.
How often does ISU–IST fly?
Turkish Airlines runs the route with about 4 flights a week (sun, mon, thu, fri). Since one carrier owns the route, a single disruption tends to ripple through the day.
What does the route health score measure?
A blend of departure-side delay at ISU and arrival-side delay at IST, computed from rolling delay windows (refreshed every 40 minutes) with a daily-rollup fallback. Current MVFR, IFR, or LIFR endpoint weather caps the score when flight rules can limit throughput. Higher is healthier: 100 means operations are clean at both ends.
