Digging into causes, Late Aircraft drives the biggest share of minutes lost, with Late Aircraft accounting for 40.1% of delay time and Carrier contributing 36.7%.

Security delays remain the smallest bucket at 0.3%. Taken together, operational and scheduling factors outweigh weather as the dominant driver of Horizon Air delays.

Seasonality matters too.
