JTR to HER questions
How long is the flight from JTR to HER?
Great-circle distance is 121 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 39–40 min gate-to-gate on this route.
How often does JTR–HER fly?
Aegean Airlines runs the route with about 3 flights a week (tue, 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 JTR 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.
