What the record says about SAT
Departures from San Antonio 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 17.7 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.
