SAL to HOU questions

Is SAL–HOU running on time right now?

Significant delay risk. The arrival side at HOU is the weaker end, route health score 38/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from SAL to HOU?

Great-circle distance is 1,912 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 165–194 min gate-to-gate on this route.

How often does SAL–HOU fly?

Southwest Airlines runs the route with about 3 flights a week (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 SAL 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.
