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