Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which normally would anchor the probability near the fleet ratio. However, no aircraft are currently equipped, and no confirmed Starlink observations exist on the ATL->RDU route. The perplexity context confirms zero equipped aircraft as of May 2026, and no recent news or sightings contradict this. Given the rollout is planned for summer 2026, the probability is anchored conservatively near zero but raised slightly to 0.30 to reflect the announced rollout and high fleet coverage expected soon.
