CGN to IST questions

Is CGN–IST running on time right now?

Some delays possible. The arrival side at IST is the weaker end, route health score 66/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from CGN to IST?

Great-circle distance is 1,968 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 169–199 min gate-to-gate on this route.

How often does CGN–IST fly?

Turkish Airlines runs the route with about 17 flights a week (daily). 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 CGN 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.
