Southwest Airlines is currently in the rolling_out phase with a high fleet coverage ratio of 86.2%, but as of the latest data, no aircraft are equipped with Starlink and no observations or sightings exist on the BNA->ORF route. The rollout is announced to begin in summer 2026, so currently no Starlink service is expected. Given the zero observations and confirmed zero equipped aircraft, the probability is anchored at 0.0 despite the high fleet coverage ratio, consistent with the airline's rollout status and verified context.
