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 yet and no confirmed Starlink observations exist on the LGB->AUS route. The rollout is announced to begin in summer 2026, so currently no Starlink service is expected. Given zero observations and no equipped aircraft, the probability is anchored at 0.0 despite the high fleet coverage ratio, consistent with the rollout timeline and lack of sightings or news.
