Southwest Airlines is currently in the rolling_out phase with a very high fleet coverage ratio of 86.2%, which would normally suggest a high probability of Starlink availability on routes. However, perplexity-verified context and recent data indicate that as of May 2026, Southwest has not yet equipped any aircraft with Starlink, and there are zero confirmed observations or sightings on the MCO->SRQ route. Given the announced rollout start in summer 2026 and no current equipped aircraft, the probability must be anchored to the empirical observation rate of 0.0%. No recent news or sightings support a higher probability at this time.
