GST delay-share reading

The standout signal at Gustavus, AK is the delay mix: Late Aircraft owns 63.5% of 3,267 delay minutes across 1,064 BTS flights. The on-time headline is 90.3% (11.3 pts above the 79% national average), with 103 delayed and 21 cancelled (1.97%).

Delay minutes concentrate in Late Aircraft (63.5% late-aircraft, 14.6% carrier, 14.2% NAS, 2.0% weather, 5.7% security). As a quieter airport, a single late inbound can swing the month more than at a mega-hub.
