Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest data. Despite a high fleet coverage ratio of 86.2% from the fleet data, this figure is not yet realized in practice since the rollout has not started and no flights on the HOU->PNS route have been observed with Starlink. There are no recent news or community sightings supporting Starlink presence on this route. Therefore, the probability is anchored at zero reflecting the current lack of deployment and observations.
