Route-specific score for PHX–SAT
Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest data. Despite a high fleet coverage ratio of 86.2% for the airline overall, this does not apply yet since the rollout has not started. There are no confirmed Starlink observations on the PHX->SAT route, no recent news indicating deployment progress, and no community sightings. Therefore, the probability of Starlink WiFi on this route is effectively zero at this time.
