FMO to HER questions
How long is the flight from FMO to HER?
Great-circle distance is 2,324 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 194–229 min gate-to-gate on this route.
How often does FMO–HER fly?
2 carriers operate this route, around 5 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 FMO and arrival-side delay at HER, 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.
