Southwest Airlines is currently in the rollout phase with a fleet coverage of 86.2%, which is high. However, there are zero observed flights with confirmed Starlink on the DAL->SNA route, and the perplexity verified context indicates that as of May 2026, no aircraft are equipped yet. No recent news or community sightings support higher probability. Given the rollout status 'rolling_out' and no confirmed equipment yet, the probability remains anchored at 0.0, reflecting the current lack of deployment despite the high fleet coverage expected in the future.
