Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which normally would imply a high probability on routes. However, perplexity verified context indicates zero aircraft currently equipped with Starlink as of May 2026, and there are no observations or sightings on this route. Given the announced rollout starting summer 2026 and no recent news or confirmed sightings, the probability is anchored conservatively at 0.30, treating the fleet ratio as a floor but not exceeding it due to lack of direct evidence on this route.
