Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which normally would anchor the probability near this level. However, there are zero observed flights with confirmed Starlink on this route and no recent news or sightings to support a higher probability. Perplexity context indicates no aircraft currently equipped, with rollout starting summer 2026. Given the rollout status and fleet coverage, the probability is anchored conservatively at 0.30, treating fleet ratio as a floor but not exceeding it due to lack of direct evidence on this route.
