MDW to SMF questions

Is MDW–SMF running on time right now?

Smooth skies ahead. The departure side at MDW is the weaker end, route health score 91/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from MDW to SMF?

Great-circle distance is 2,874 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 233–276 min gate-to-gate on this route.

How often does MDW–SMF fly?

Southwest Airlines runs the route with about 14 flights a week (daily). 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 MDW and arrival-side delay at SMF, 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.
