What the record says about BOS

BOS runs about as well as the average airport here.

The airlines flying from here are not equally affected. Virgin Atlantic left on time 24 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, BOS 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.
