ITH delay-share reading

The standout signal at Ithaca/Cortland, NY is on-time standing: 87.6% (8.6 pts above the 79% national flight-weighted average; roughly the top-quartile on-time performance) across 6,186 BTS flights (2020–2025). When a departure runs late, the average delay is 96.2 minutes; cancellations run 1.92%.

Delay minutes concentrate in Late Aircraft (34.4% late-aircraft, 32.6% carrier, 14.1% NAS, 18.6% weather, 0.3% security). As a quieter airport, a single late inbound can swing the month more than at a mega-hub.
