Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which would normally suggest a high probability of Starlink presence 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 sightings on the MSY->LAX route. Given the announced rollout starting summer 2026 and no recent news or sightings, the probability is anchored conservatively at 0.30, the floor set by the fleet coverage for rolling_out airlines, reflecting the expected near-future deployment rather than current presence.
