Southwest Airlines currently has a fleet coverage of 86.2% planned but has not yet equipped any aircraft with Starlink as of the latest data (May 2026). The rollout status is 'rolling_out' with an announced start in summer 2026, and no confirmed Starlink observations or community sightings exist on the SMF->SBA route. Given the zero observed Starlink rate and the airline's announcement that no aircraft are currently equipped, the probability is anchored at 0.0 despite the high fleet coverage planned. No recent news or sightings suggest earlier deployment on this route.
