Southwest Airlines currently has a fleet coverage of 0% for Starlink despite an announced rollout starting summer 2026. The fleet coverage data shows 733 of 850 aircraft equipped is inconsistent with the perplexity verified context stating zero equipped currently, indicating the fleet data may be projected or incorrect. No flights observed on the SAT->MDW route have confirmed Starlink, and there are no recent news or community sightings supporting presence on this route. Given the rollout status is 'rolling_out' but with zero current equipped aircraft, the probability is anchored at 0.0 reflecting no empirical evidence or confirmed deployment yet.
