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 reflects the entire fleet potential once rollout is complete, not current status. There are no confirmed Starlink observations on the AUS->BOS route, no recent news indicating active deployment, and no community sightings. Given the announced status and zero equipped aircraft, the probability of Starlink on this route is effectively zero at this time.
