Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which would normally suggest a high probability of Starlink presence on routes. However, there are zero observed flights with confirmed Starlink on the AUS->LGB route, and no recent news or community sightings to support a higher probability. Perplexity context indicates that as of May 2026, Southwest has not yet equipped any aircraft with Starlink, with rollout expected to begin in summer 2026. Given these factors, the probability is anchored conservatively at 0.30, which is the floor for rolling_out airlines with fleet coverage above 0.30, reflecting the announced rollout but lack of current evidence.
