Southwest Airlines is currently in the rollout phase for Starlink with a high fleet coverage ratio of 86.2%, which normally would suggest a high probability on routes. However, perplexity-verified context indicates zero aircraft currently equipped, and there are no confirmed observations or community sightings on the MDW->BUR route. The rollout is announced to begin in summer 2026, so no active installations exist yet. Given these factors, the probability is anchored at 0.0, reflecting no current Starlink presence despite the high fleet coverage planned for the future.
