LAS to GSP questions
Is LAS–GSP running on time right now?
Smooth skies ahead. The departure side at LAS is the weaker end, route health score 90/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from LAS to GSP?
Great-circle distance is 2,970 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 240–285 min gate-to-gate on this route.
How often does LAS–GSP fly?
Southwest Airlines runs the route with about 1 flight a week (mon). 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 LAS and arrival-side delay at GSP, 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.
