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 that level. However, there are zero observed flights with confirmed Starlink on the BNA->DTW route, and no recent news or community sightings to support a higher probability. Additionally, Southwest has announced rollout beginning summer 2026 with no current equipped aircraft as of May 2026, indicating that the fleet coverage figure likely reflects planned rather than actual current equipment. Given these factors, the probability is anchored conservatively at 0.30, reflecting the rollout status and fleet coverage as a floor but not exceeding it due to lack of direct evidence.
