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 AUS->SLC route. Given the fleet coverage is high but no aircraft are equipped yet, and no recent news or sightings confirm Starlink presence on this route, the probability is anchored at 0.0 reflecting the current empirical observation and rollout status.
