Southwest Airlines currently has a fleet coverage of 86.2% but has not yet equipped any aircraft with Starlink as of the latest verified context. The rollout status is 'rolling_out' with an announced start in summer 2026 and no confirmed Starlink-equipped aircraft currently. There are zero observed flights with Starlink on the MDW->IND route and no recent news or community sightings to suggest otherwise. Given the airline's announcement and high fleet coverage target, the probability will remain anchored at 0.0 until actual equipment or observations occur, reflecting the current reality conservatively.
