Southwest Airlines currently has 0% of its fleet equipped with Starlink, despite an overall fleet coverage ratio of 86.2% reported for the airline group. However, the perplexity verified context clarifies that Southwest has announced a Starlink rollout starting summer 2026, with no aircraft equipped as of May 2026. There are zero confirmed Starlink observations on the DTW-PHX route, and no recent news or community sightings support higher probability. Given the rollout status is 'rolling_out' but actual equipped count is zero, the probability must reflect the current empirical reality rather than fleet coverage. Therefore, the probability is anchored at 0.0 with high confidence that Starlink is not yet available on this route.
