Route-specific score for ONT–SJC
Southwest Airlines is currently in the rollout phase with a high fleet coverage ratio of 86.2%, which would normally suggest a high probability of Starlink availability on routes. However, perplexity-verified context indicates that as of May 2026, Southwest has not yet equipped any aircraft with Starlink, and there are zero confirmed observations or community sightings on the ONT->SJC route. Given the announced rollout starting summer 2026 and no recent news or sightings, the probability is anchored low, slightly above zero to reflect imminent rollout but no current evidence.
