FRA to SJO questions
Is FRA–SJO running on time right now?
Mostly on schedule. The departure side at FRA is the weaker end, route health score 70/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from FRA to SJO?
Great-circle distance is 9,354 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 690–832 min gate-to-gate on this route.
How often does FRA–SJO fly?
Lufthansa 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 FRA and arrival-side delay at SJO, 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.
