Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which normally would anchor the probability near this level. However, no flights have been observed with confirmed Starlink on the CMH->SAN route, and perplexity-verified context indicates zero aircraft currently equipped as of May 2026, with rollout expected to begin in summer 2026. No recent news or community sightings support a higher probability. Given the rollout status and fleet coverage, the probability is anchored conservatively at 0.30, reflecting the announced rollout but lack of current equipment or observations.
