Southwest Airlines is currently in a rolling_out status with a very high fleet coverage ratio of 86.2%, which would normally imply a high probability of Starlink presence on routes. However, perplexity-verified context and recent data confirm that as of May 2026, Southwest has not yet equipped any aircraft with Starlink. There are zero confirmed observations or community sightings on the MIA->PIT route, and no recent news indicating deployment progress. Given the announced rollout start in summer 2026 and zero current equipped aircraft, the probability must be anchored at zero despite the high fleet coverage ratio, reflecting the current lack of deployment rather than incomplete data.
