Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, indicating a strong likelihood of Starlink installation on their aircraft soon. However, there are zero observed flights with confirmed Starlink on the SYR->GSO route, and no recent news or community sightings to confirm active deployment. Given the rollout is announced but not yet installed, and the fleet coverage is high but empirical observation is zero, the probability is anchored conservatively at 0.30, reflecting the rollout status and fleet coverage floor without exceeding it by more than 0.10.
