Southwest Airlines is currently in the rollout phase with a high fleet coverage ratio of 86.2%, which normally would suggest a high probability of Starlink presence on routes. However, perplexity-verified context and recent data indicate that as of May 2026, Southwest has not yet equipped any aircraft with Starlink, and there are zero confirmed observations on the ELP->AUS route. No recent news or community sightings support higher probability. Given the rollout status and zero current equipment, the probability is anchored at zero, reflecting the current lack of Starlink installation despite the high fleet coverage ratio planned for the future.
