Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which would normally anchor the probability near this level. However, perplexity-verified context and recent news confirm that as of May 2026, Southwest has not yet equipped any aircraft with Starlink, and no confirmed sightings or observations exist on the BUR->BNA route. Given the announced rollout start in summer 2026 and zero observed Starlink flights, the probability must remain anchored at 0.0, reflecting the current lack of deployment despite the high fleet coverage ratio. The confidence in this estimate is high due to strong official announcements and absence of contrary evidence.
