Southwest Airlines currently has a fleet coverage of 86.2% but has not yet equipped any aircraft with Starlink as of May 2026, with rollout announced to begin in summer 2026. There are zero observed flights with Starlink on the SJC->MDW route, no recent news indicating early deployment, and no community sightings. Given the rollout status is 'rolling_out' but no aircraft are equipped yet, the probability remains anchored at 0.0. The high fleet coverage does not apply here since the fleet is not yet equipped, and the rollout has not started. Therefore, the probability is conservatively set to zero with high confidence in this estimate.
