Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which normally would anchor the probability near that level. However, perplexity-verified context and recent news confirm that as of mid-2026, Southwest has not yet equipped any aircraft with Starlink, and there are zero confirmed observations or sightings on this route. Given the announced rollout starting summer 2026 and no current equipped aircraft, the probability is anchored conservatively near 0.30 (floor for rolling_out airlines with fleet_ratio >= 0.30) rather than the fleet coverage ratio, reflecting the early rollout phase and lack of direct evidence.
