Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which normally would set a high floor for probability. However, perplexity verified context and recent data indicate zero aircraft currently equipped with Starlink and no confirmed observations on this route. Given the announced rollout starting summer 2026 and no recent sightings or news, the probability is anchored conservatively near the lower bound of rollout expectations, set at 0.30 to reflect the rollout status and fleet coverage while respecting the lack of empirical observations.
