Cancellations are counted against everything scheduled. Diverted flights are counted with them rather than as very late arrivals, which is why the on-time share and the cancellation rate do not add up to everything that happened.

Airline by airline

Airlines with at least 100 flights on SAT–PHX, busiest first. Same route, same weather, same air traffic — which makes this the fairest comparison on the site.

American Airlines 83.2% 109 min 0.7% 3,279
SkyWest Airlines 85% 0% 153

A dash under typical delay means fewer than 30 of that airline’s flights arrived 15 minutes late or more — too few to average.
