What the record says about PHL

Departures from Philadelphia run late more often than average — enough that a tight connection at the far end deserves a second look.

The airlines flying from here are not equally affected. Delta Air Lines left on time 14 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, PHL 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.
