Southwest Airlines is currently in a rolling_out 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 and recent data confirm that as of May 2026, Southwest has not yet equipped any aircraft with Starlink, and no observations or sightings exist on the RNO->DAL route. Given the announced rollout start in summer 2026 and zero current equipped aircraft, the probability must be anchored at zero despite the high fleet coverage ratio. No recent news or sightings contradict this, so the probability remains very low.
