Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest data. Despite a high overall fleet coverage ratio of 86.2% reported, this figure likely reflects future projections or other airlines, as Southwest specifically has zero equipped aircraft currently. There are no confirmed observations or community sightings on the LBB->AUS route, and no recent news indicating active deployment. Given the rollout status is 'rolling_out' but with zero equipped aircraft and no route-specific evidence, the probability is anchored at 0.0 with low likelihood of Starlink availability on this route at this time.
