Southwest Airlines currently has zero aircraft equipped with Starlink despite a high fleet coverage ratio of 86.2% expected by end-2026. The rollout status is 'rolling_out' with no confirmed Starlink-equipped flights observed on the SRQ->BNA route, no recent news, and no community sightings. Given the announced rollout is planned for summer 2026 and current data shows zero equipped aircraft, the probability remains anchored at 0.0. The fleet coverage ratio is not yet applicable as no aircraft are equipped, so the probability cannot be raised based on fleet ratio. Therefore, the probability is conservatively set to zero with high confidence.
