Southwest Airlines is currently in the rollout phase with a high fleet coverage ratio of 86.2%, indicating a strong likelihood of Starlink installation on their aircraft in the near future. However, there are zero observed flights with confirmed Starlink on the PIT->SRQ route, and no recent news or community sightings to support a higher probability. The rollout is announced to begin in summer 2026, and as of the latest data, no aircraft are equipped yet. Given the rollout status and fleet coverage, the probability is anchored conservatively at 0.30, reflecting the announced rollout and fleet coverage as a floor, but not exceeding it due to lack of direct observations or sightings.
