How the San Francisco to Cahokia/St Louis route actually runs

SFO to CPS questions
Is SFO–CPS running on time right now?
Smooth skies ahead. The departure side at SFO is the weaker end, route health score 92/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from SFO to CPS?
Great-circle distance is 2,807 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 228–271 min gate-to-gate on this route.
How often does SFO–CPS fly?
Delta Air Lines runs the route with about 1 flight a week (wed). 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 SFO and arrival-side delay at CPS, 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.
