Southwest Airlines is currently in the rollout phase for Starlink with a high fleet coverage ratio of 86.2%, which would normally suggest a high probability on most 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 community sightings on the BWI->CLT route. No recent news supports earlier deployment. Given the rollout status 'rolling_out' and the lack of any confirmed equipped aircraft, the probability is anchored at zero despite the high fleet coverage ratio, reflecting the current absence of Starlink on Southwest aircraft.
