Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, but perplexity-verified context and recent data confirm that as of May 2026, no aircraft are equipped with Starlink yet. There are zero confirmed observations or sightings on the BWI->GRR route, and no recent news indicating active deployment. Given the announced rollout starting summer 2026 and zero current equipment, the probability remains at 0.0, reflecting the current lack of Starlink on this airline despite the high fleet coverage ratio planned for the future.
