Southwest Airlines is currently in the rolling_out phase with a high fleet coverage ratio of 86.2%, indicating a strong likelihood of Starlink installation on their aircraft. However, there are zero observed flights with confirmed Starlink on the LAS->TUL route and no recent news or community sightings to support a higher probability. Perplexity context confirms no current equipped aircraft as of May 2026, with rollout expected to begin in summer 2026. Given the rollout status and fleet coverage, the probability is anchored conservatively at 0.30, reflecting the fleet ratio floor for rolling_out airlines, despite zero observations.
