MSY to SAN questions
Is MSY–SAN running on time right now?
Some delays possible. The departure side at MSY 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 MSY to SAN?
Great-circle distance is 2,568 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 211–250 min gate-to-gate on this route.
How often does MSY–SAN fly?
Southwest Airlines runs the route with about 6 flights a week (sun, mon, tue, wed, thu, 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 MSY and arrival-side delay at SAN, 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.
