STL to SBD questions

Is STL–SBD running on time right now?

Mostly on schedule. The departure side at STL is the weaker end, route health score 80/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from STL to SBD?

Great-circle distance is 2,449 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 203–240 min gate-to-gate on this route.

How often does STL–SBD fly?

Sun Country Airlines runs the route with about 7 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 STL and arrival-side delay at SBD, 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.
