MIA delay-share reading

The standout signal at Miami, FL is traffic scale: 1,160,127 BTS flights (2020–2025) place it #21 of 382 by book size. That busy-book footprint sits beside a 77.9% on-time rate (1.1 pts below the 79% national flight-weighted average), 256,336 delayed departures, and 11,802 cancellations (1.02% of the book).

Delay minutes concentrate in Late Aircraft (37.5% late-aircraft, 35.8% carrier, 20.4% NAS, 5.9% weather, 0.3% security). As a busy airport, that mix matters more for connection planning than for a thin schedule.

On the multi-year calendar, MIA is strongest in October (91.4% on-time) and weakest in June (84.7%), a 6.7-point swing. Volume peaks in March (~18,588 flights/month). The busiest connecting route is to ATL (Atlanta) at 76.7% on-time. Field definitions: on-time performance explained.
