Southwest Airlines currently has a high fleet coverage ratio of 86.2%, which would normally suggest a high probability of Starlink presence on routes. However, the rollout status is 'rolling_out' with no aircraft currently equipped, no confirmed observations on the DAL->RDU route, and no recent news or sightings supporting active deployment. Given the announced rollout starting summer 2026 and zero current equipped aircraft, the probability is anchored low, slightly above zero to reflect imminent rollout but no current evidence.
