ATH to OPO questions

Is ATH–OPO running on time right now?

Smooth skies ahead. The departure side at ATH is the weaker end, route health score 85/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from ATH to OPO?

Great-circle distance is 2,803 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 228–270 min gate-to-gate on this route.

How often does ATH–OPO fly?

Aegean Airlines S.A. 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 ATH and arrival-side delay at OPO, 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.
