Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which would normally anchor the probability near this value. However, there are zero observed flights with confirmed Starlink on the HOU->VPS route and no recent news or sightings to support a higher probability. Perplexity context indicates no aircraft currently equipped as of May 2026, with rollout starting summer 2026. Given the rollout status and fleet coverage, the probability is anchored conservatively at 0.30, reflecting the announced rollout but lack of empirical confirmation on this route.
