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 BNA->VPS route. Given zero observed flights with Starlink and no recent news indicating early deployment on this route, the probability must be anchored to the empirical observation rate of 0.0%. Although the fleet coverage is high, the rollout has not started, so the probability remains at zero with high confidence.
