OTP to SOF questions

Is OTP–SOF running on time right now?

Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from OTP to SOF?

Great-circle distance is 300 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 51–56 min gate-to-gate on this route.

How often does OTP–SOF fly?

TAROM runs the route with about 5 flights a week (mon, tue, wed, thu, sat). 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 OTP and arrival-side delay at SOF, 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.
