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 ROC->BWI route. The perplexity context indicates rollout begins summer 2026 with no current equipped aircraft. Given zero observations and no recent news or sightings, the probability remains anchored at 0.0. Although the fleet coverage is high, the rollout has not started, so the fleet ratio floor rule for installed or fully_deployed airlines does not apply here.
