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, perplexity-verified context and recent data indicate zero aircraft currently equipped and zero confirmed observations on the RSW->DAL route. Given the rollout is announced but not yet started, and no recent news or sightings support higher probability, the score is anchored conservatively at 0.30, reflecting the fleet coverage as a floor but acknowledging the rollout status and lack of empirical evidence.
