IKA to IST questions
Is IKA–IST running on time right now?
High disruption likely. The arrival side at IST is the weaker end, route health score 0/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from IKA to IST?
Great-circle distance is 2,052 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 175–206 min gate-to-gate on this route.
How often does IKA–IST fly?
6 carriers operate this route, around 46 flights a week between them. Compare carrier days and times in the airline list above.
What does the route health score measure?
A blend of departure-side delay at IKA 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.
