LWS delay-share reading

The standout signal at Lewiston, ID is the delay mix: Carrier owns 66.1% of 65,488 delay minutes across 10,808 BTS flights. The on-time headline is 89.7% (10.7 pts above the 79% national average), with 1,112 delayed and 39 cancelled (0.36%).

Delay minutes concentrate in Carrier (10.0% late-aircraft, 66.1% carrier, 3.4% NAS, 20.3% weather, 0.2% security). Mid-volume books still show a clear delay fingerprint rather than a weather-only story.
