What the record says about SAN

SAN is one of the later-running airports in the record. When an airport is this congested the cause is usually structural — runway capacity, airspace, or a hub airline scheduling more departures into a peak than the field can clear — and no airline flying from it escapes entirely.

The airlines flying from here are not equally affected. Delta Air Lines left on time 28.3 points more often than Southwest Airlines from the same airport — which is the clearest evidence available that a delayed departure is not purely the airport's fault.

With 40 routes in the record, SAN is a hub, and hubs carry a particular risk: a delay early in the day propagates through every aircraft that was due to fly on afterwards. Morning departures from a hub are reliably better than evening ones.
