Southwest Airlines is currently in the 'rolling_out' phase with a high fleet coverage ratio of 86.2%, but as of the latest data (2026-05-20), no aircraft are equipped yet and no confirmed Starlink observations exist on the RDU->ATL route. The rollout is announced to begin in summer 2026, so no current deployments are expected. Given zero observations and no confirmed equipment, the probability is anchored at 0.0 despite the high fleet coverage ratio, reflecting the current lack of deployment.
