Pro Flight Search records official board updates for nonstop HER to SOF 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.

HER to SOF questions
Is HER–SOF running on time right now?
Some delays possible. The arrival side at SOF 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 HER to SOF?
Great-circle distance is 832 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 89–101 min gate-to-gate on this route.
How often does HER–SOF fly?
Bulgaria Air runs the route with about 2 flights a week (sun, thu). 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 HER 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.
