Southwest Airlines currently has zero aircraft equipped with Starlink and a rollout status of 'rolling_out' with fleet coverage effectively 0%. Although the overall fleet coverage data shows 86.2%, this is inconsistent with the verified context stating zero equipped aircraft as of May 2026 and no confirmed sightings or observations on this route. No recent news or community sightings support higher probability. Given the announced rollout starting summer 2026, it is premature to assign any meaningful probability for Starlink availability on the MDW->ROC route at this time.
