Southwest Airlines currently has a fleet coverage of 86.2% planned but has not yet equipped any aircraft with Starlink as of the latest update. The rollout status is 'rolling_out' with an announced start in summer 2026, and no confirmed Starlink observations or sightings on the MDW->SAN route. Given zero observations and no recent news indicating active deployment, the probability is anchored at 0.0. Although the fleet coverage is high, the rollout has not started, so the fleet ratio floor rule does not apply here.
