MMH delay-share reading

The standout signal at Mammoth Lakes, CA is traffic scale: 540 BTS flights (2020–2020) place it #373 of 382 by book size. That quiet-book footprint sits beside a 80.7% on-time rate (1.7 pts above the 79% national flight-weighted average), 104 delayed departures, and 71 cancellations (13.15% of the book).

Delay minutes concentrate in Carrier (29.5% late-aircraft, 30.4% carrier, 14.3% NAS, 25.8% weather, 0.0% security). As a quieter airport, a single late inbound can swing the month more than at a mega-hub.

On the multi-year calendar, MMH is strongest in March (92.8% on-time) and weakest in February (83.3%), a 9.5-point swing. Volume peaks in January (~186 flights/month). Field definitions: on-time performance explained.
