BWI delay-share reading

The standout signal at Baltimore, MD is traffic scale: 1,049,006 BTS flights (2020–2025) place it #23 of 382 by book size. That busy-book footprint sits beside a 78% on-time rate (1 pts below the 79% national flight-weighted average), 230,270 delayed departures, and 13,150 cancellations (1.25% of the book).

Delay minutes concentrate in Carrier (38.2% late-aircraft, 38.9% carrier, 18.9% NAS, 3.7% 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, BWI is strongest in February (90.6% on-time) and weakest in July (82.2%), a 8.4-point swing. Volume peaks in July (~15,960 flights/month). The busiest connecting route is to ATL (Atlanta) at 80.2% on-time. Field definitions: on-time performance explained.
