What the record says about IDA
Departures from IDA leave close to schedule more often than most airports in the record. An airport this punctual is usually one with spare capacity in its runway slots.
The airlines flying from here are not equally affected. Delta Air Lines left on time 16.3 points more often than Allegiant Air from the same airport — which is the clearest evidence available that a delayed departure is not purely the airport's fault.
