Southwest Airlines is currently in rollout status with a high fleet coverage ratio of 86.2%, which would normally suggest a high probability of Starlink presence on routes. However, perplexity-verified context indicates zero aircraft currently equipped, with rollout starting in summer 2026 and no confirmed Starlink sightings or observations on this route. Given zero observed flights with Starlink and no recent news or sightings, the probability is anchored at 0.0 despite the high fleet coverage, reflecting the current lack of deployment.
