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 indicates zero aircraft currently equipped and no confirmed Starlink observations on the CVG-PHX route. Recent news and community sightings provide no additional evidence. Given the rollout is announced to begin in summer 2026 and no aircraft are equipped yet, the probability is anchored conservatively near zero but not zero due to the high fleet coverage and rollout status, setting a floor at 0.30 as per critical scoring rules for rolling_out airlines with fleet_ratio >= 0.30.
