Southwest Airlines is currently in the rolling_out phase with a high fleet coverage ratio of 86.2%, which normally would anchor the probability near that level. However, perplexity-verified context and recent data confirm that as of May 2026, Southwest has not yet equipped any aircraft with Starlink, and there are zero confirmed observations or sightings on the MCO->LAS route. Given the announced rollout start in summer 2026 and no recent news or sightings, the probability is anchored low near zero but slightly elevated to 0.10 to reflect imminent rollout plans and high fleet coverage potential.
