Southwest Airlines is currently in the rollout phase with a high fleet coverage ratio of 86.2%, indicating a strong likelihood of Starlink installation on many aircraft. However, no flights have been observed with confirmed Starlink on the MCI->FLL route, and perplexity data shows zero equipped aircraft as of May 2026. Given the rollout status and high fleet coverage, the probability is anchored to a conservative floor of 0.30, reflecting the announced rollout and expected near-future coverage rather than current empirical observations. No recent news or community sightings support a higher probability at this time.
