Southwest Airlines currently has a high fleet coverage ratio of 86.2%, which would normally suggest a high probability of Starlink availability on most routes. However, the rollout status is 'rolling_out' with no aircraft currently equipped, and no confirmed Starlink observations or community sightings on the SLC->SJC route. Additionally, perplexity-verified context confirms zero equipped aircraft as of May 2026. Given these factors, the probability is anchored at 0.0, reflecting the current lack of deployment despite the high fleet coverage ratio. No recent news or sightings suggest earlier deployment on this route.
