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% reported, this figure is not yet realized in practice since the rollout is scheduled to begin in summer 2026 and no confirmed Starlink-equipped flights have been observed on the HOU->JAN route. There is no recent news or community sightings to suggest earlier deployment on this route. Therefore, the probability is anchored at zero reflecting the current lack of equipped aircraft and observations.
