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 overall fleet (likely projected or for future rollout), no flights on the BNA->GSP route have confirmed Starlink equipment, and there are no recent news or community sightings supporting active deployment. The rollout is expected to begin in summer 2026, so current probability remains at zero reflecting no active installations yet.
