Southwest Airlines currently has zero aircraft equipped with Starlink despite an announced rollout starting summer 2026. The fleet coverage is high (86.2%) but this reflects future expectations, not current status. No observations or sightings confirm Starlink on the BNA->BOS route, and no recent news updates indicate active deployment. Given rollout_status is 'rolling_out' but with zero equipped aircraft, the probability must be anchored at 0.0, reflecting current reality rather than future plans.
