ATL delay-share reading

The standout signal at Atlanta, GA is traffic scale: 3,758,561 BTS flights (2020–2025) place it #1 of 382 by book size. That busy-book footprint sits beside a 83.7% on-time rate (4.7 pts above the 79% national flight-weighted average), 613,025 delayed departures, and 29,771 cancellations (0.79% of the book).

Delay minutes concentrate in Carrier (27.2% late-aircraft, 46.8% carrier, 19.4% NAS, 6.4% weather, 0.2% security). As a busy airport, that mix matters more for connection planning than for a thin schedule.

On the multi-year calendar, ATL is strongest in November (93.6% on-time) and weakest in July (86.7%), a 6.9-point swing. Volume peaks in March (~56,563 flights/month). The busiest connecting route is to MCO (Orlando) at 78.1% on-time. Field definitions: on-time performance explained.
