Southwest Airlines is currently in the rollout phase for Starlink with a high fleet coverage ratio of 86.2%, but as of the latest data (2026-05-20), no aircraft are equipped yet. There are zero confirmed Starlink observations on the BWI->SJC route, no recent news indicating active deployment, and no community sightings. Given the announced rollout status and zero current equipment, the probability remains anchored at 0.0, reflecting the current lack of operational Starlink on Southwest aircraft despite the high fleet coverage planned for the future.
