How to read these numbers
On-time rate is the share of flights within 15 minutes of schedule (US DOT standard). Taxi-out time and cancellation rate are leading indicators of surface and schedule pressure: long taxi-out points to runway/ramp congestion, while a high cancellation rate often reflects weather exposure. Hubs concentrate connecting traffic, so a delay here can ripple network-wide — build in a buffer when connecting through LAX.
