MEX to SAL questions
How long is the flight from MEX to SAL?
Great-circle distance is 1,259 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 119–138 min gate-to-gate on this route.
How often does MEX–SAL fly?
Avianca runs the route with about 7 flights a week (daily). 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 MEX and arrival-side delay at SAL, 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.
