Pro Flight Search — Miami (MIA) to Santiago (STI) route reliability, measured from operated flights on official airport boards.

Mostly on schedule. The departure side at MIA is the weaker end, route health score 78/100. The airports section above carries the live status and delay window at both ends.
Great-circle distance is 1,221 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 116–135 min gate-to-gate on this route.
American Airlines 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.
A blend of departure-side delay at MIA and arrival-side delay at STI, 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.
