SDF to HOU questions
Is SDF–HOU running on time right now?
Some delays possible. The arrival side at HOU is the weaker end, route health score 52/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from SDF to HOU?
Great-circle distance is 1,293 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 121–141 min gate-to-gate on this route.
How often does SDF–HOU fly?
Southwest Airlines runs the route with about 5 flights a week (sun, mon, thu, fri, sat). 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 HOU, 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.
