Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which normally would suggest a high probability of Starlink presence on routes. However, there are zero observed flights with confirmed Starlink on the MSY->RDU route, and perplexity data indicates zero aircraft currently equipped as of May 2026. The rollout is announced to begin in summer 2026, so actual installations are not yet present. Given the rollout status and fleet coverage, the fleet ratio acts as a floor, but due to no confirmed installations or sightings, the probability is anchored conservatively at 0.30, reflecting the announced rollout and expected near-future coverage rather than current presence.
