Southwest Airlines is currently in the rolling_out phase with a 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 confirm that as of May 2026, Southwest has not yet equipped any aircraft with Starlink. There are zero observed flights with Starlink on the LAS->BHM route, and no recent news or community sightings indicate deployment progress. Given the rollout status and zero current equipment, the probability is anchored at 0.0, reflecting the current lack of Starlink-equipped aircraft despite the high fleet coverage ratio planned for the future.
