Southwest Airlines is currently in a rolling_out status with a high fleet coverage ratio of 86.2%, but as of the latest data, no aircraft are equipped and no Starlink observations exist on the FLL->DCA route. The perplexity context confirms zero equipped aircraft as of May 2026, with rollout expected to begin in summer 2026. Given the high fleet coverage ratio but zero current equipment and observations, the probability is anchored conservatively at 0.30, reflecting the rollout status and expected near-future coverage rather than the fleet ratio itself. No recent news or sightings support a higher probability.
