Southwest Airlines currently has a fleet coverage of 86.2% but is in the 'rolling_out' status with zero aircraft equipped as of the latest verified context. No flights on the SAN->MCI route have confirmed Starlink tails, and there are no recent news or community sightings supporting Starlink presence on this route. Although the fleet coverage is high, the rollout has not yet begun, so the probability is anchored at zero based on empirical observation and confirmed rollout status.
