What the record says about BOI

BOI runs about as well as the average airport here.

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.
