Southwest Airlines is currently in the rolling_out phase with a high fleet coverage ratio of 86.2%, indicating a strong eventual presence of Starlink. However, as of the latest data, no aircraft are equipped yet and no confirmed Starlink sightings or observations exist on the MCO->RIC route. The perplexity context confirms zero equipped aircraft as of May 2026, and no recent news or community sightings support higher probability. Given the rollout status and zero observations, the probability remains anchored at 0.0, reflecting current reality rather than fleet potential.
