SUN delay-share reading

The standout signal at Sun Valley/Hailey/Ketchum, ID is the delay mix: Carrier owns 45.0% of 160,921 delay minutes across 22,928 BTS flights. The on-time headline is 88.6% (9.6 pts above the 79% national average), with 2,622 delayed and 328 cancelled (1.43%).

Delay minutes concentrate in Carrier (15.6% late-aircraft, 45.0% carrier, 15.2% NAS, 24.1% weather, 0.1% security). Mid-volume books still show a clear delay fingerprint rather than a weather-only story.
