Southwest Airlines is currently in the rolling_out phase with a high fleet coverage ratio of 86.2%, but as of the latest data (2026-05-20), no aircraft are equipped yet and no flights on the IND->SRQ route have confirmed Starlink tails. The perplexity-verified context confirms zero equipped aircraft with high confidence, and there are no recent news or community sightings supporting Starlink presence on this route. Given the rollout status and zero observations, the probability remains anchored at 0.0, reflecting the current lack of deployment despite the high fleet coverage ratio expected in the future.
