Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest update. Despite a high fleet coverage ratio of 86.2% from the fleet data, this figure is not yet realized since rollout has not started and no Starlink-equipped aircraft have been observed on the DAL->RSW route or elsewhere. No recent news or community sightings support higher probability. Therefore, the probability is anchored at 0.0 reflecting the current lack of equipped aircraft and observations.
