BSZ to IST questions

Is BSZ–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 often does BSZ–IST fly?

Turkish Airlines runs the route with about 18 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 BSZ 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.
