Southwest Airlines is currently in the rolling_out phase with a very high fleet coverage ratio of 86.2%, which would normally anchor the probability near this level. However, perplexity-verified context and recent data confirm that as of May 2026, Southwest has not yet equipped any aircraft with Starlink, and there are zero confirmed observations or sightings on this route. No recent news indicates any change. Given the rollout has not started and no empirical evidence supports Starlink presence, the probability is anchored at zero despite the high fleet coverage ratio.
