HOU to SLC questions
Is HOU–SLC running on time right now?
Smooth skies ahead. The departure side at HOU is the weaker end, route health score 85/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from HOU to SLC?
Great-circle distance is 1,953 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 168–197 min gate-to-gate on this route.
How often does HOU–SLC fly?
Southwest Airlines runs the route with about 5 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 HOU and arrival-side delay at SLC, 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.
