Southwest Airlines is currently in the rolling_out phase with a high fleet coverage ratio of 86.2%, but as of the latest data (2026-05-20), no aircraft are equipped yet and no confirmed Starlink observations exist on the SBA->OAK route. The rollout is announced to begin in summer 2026, so no active deployments are expected at this time. Given zero observations and no equipped aircraft, the probability is anchored at 0.0 despite the high fleet coverage ratio, reflecting the current lack of deployment.
