Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, which normally would imply a high probability of Starlink presence on routes. However, perplexity-verified context and recent data indicate that as of mid-2026, Southwest has not yet equipped any aircraft with Starlink, and there are zero confirmed observations on the LBB->LAS route. Given the announced rollout starting summer 2026 and no recent sightings or news, the probability is anchored conservatively near the lower bound of the fleet coverage floor rule for rolling_out airlines, set here at 0.30 to reflect the imminent but not yet realized deployment.
