Southwest Airlines is currently in the rollout phase with a high fleet coverage ratio of 86.2%, but no aircraft are yet equipped as of the latest data. There are zero confirmed Starlink observations on the MDW->MSY route, and no recent news or community sightings to suggest active deployment on this route. Given the announced rollout starting summer 2026 and the high fleet coverage target, the probability is anchored conservatively at 0.30, reflecting the fleet coverage floor for rolling_out airlines with fleet_ratio >= 0.30, but not exceeding the empirical observation rate by more than 0.10 due to lack of direct evidence.
