BOS delay-share reading

The standout signal at Boston, MA is traffic scale: 1,455,478 BTS flights (2020–2025) place it #14 of 382 by book size. That busy-book footprint sits beside a 79.9% on-time rate (0.9 pts above the 79% national flight-weighted average), 292,211 delayed departures, and 17,391 cancellations (1.19% of the book).

Delay minutes concentrate in Carrier (34.4% late-aircraft, 37.1% carrier, 25.0% NAS, 3.4% weather, 0.1% security). As a busy airport, that mix matters more for connection planning than for a thin schedule.

On the multi-year calendar, BOS is strongest in November (92.8% on-time) and weakest in July (88%), a 4.8-point swing. Volume peaks in March (~21,852 flights/month). The busiest connecting route is to DCA (Washington) at 81.6% on-time. Field definitions: on-time performance explained.
