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 route-specific observations or recent news confirming Starlink presence on MCI->RSW. Given the rollout is announced but not yet started, and no confirmed sightings exist, 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.
