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% projected for the future, no flights on the DAL->SJC route have confirmed Starlink equipment, and there are no recent news or community sightings supporting active deployment. Given the rollout status is 'rolling_out' but actual equipped aircraft count is zero, the probability must reflect the current lack of deployment rather than the future fleet ratio.
