BOI delay-share reading

The standout signal at Boise, ID is the delay mix: Carrier owns 41.3% of 1,260,417 delay minutes across 266,753 BTS flights. The on-time headline is 85.2% (6.2 pts above the 79% national average), with 39,406 delayed and 1,457 cancelled (0.55%).

Delay minutes concentrate in Carrier (33.3% late-aircraft, 41.3% carrier, 19.1% NAS, 6.1% 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, BOI is strongest in October (94.8% on-time) and weakest in December (91.5%), a 3.3-point swing. Volume peaks in August (~4,046 flights/month). The busiest connecting route is to SEA (Seattle) at 86% on-time. Field definitions: on-time performance explained.
