SCK delay-share reading

The standout signal at Stockton, CA is on-time standing: 72.6% (6.4 pts below the 79% national flight-weighted average; roughly the bottom-quartile on-time performance) across 7,206 BTS flights (2020–2025). When a departure runs late, the average delay is 78.7 minutes; cancellations run 2.32%.

Delay minutes concentrate in Late Aircraft (46.2% late-aircraft, 26.4% carrier, 15.9% NAS, 10.1% weather, 1.4% security). As a quieter airport, a single late inbound can swing the month more than at a mega-hub.
