COS to SAN questions
Is COS–SAN running on time right now?
Significant delay risk. The arrival side at SAN is the weaker end, route health score 46/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from COS to SAN?
Great-circle distance is 1,312 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 123–142 min gate-to-gate on this route.
How often does COS–SAN fly?
Southwest Airlines runs the route with about 3 flights a week (mon, thu, fri). 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 COS and arrival-side delay at SAN, 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.
