How the Louisville to San Francisco route actually runs
Pro Flight Search records official board updates for nonstop SDF to SFO flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

SDF to SFO questions
Is SDF–SFO running on time right now?
Significant delay risk. The arrival side at SFO is the weaker end, route health score 42/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from SDF to SFO?
Great-circle distance is 3,194 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 255–304 min gate-to-gate on this route.
How often does SDF–SFO fly?
Breeze Airways runs the route with about 2 flights a week (mon, 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 SDF and arrival-side delay at SFO, 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.
