Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest data. Despite a high fleet coverage ratio of 86.2% for the airline overall, this reflects future expectations rather than current reality. There are no confirmed Starlink observations on the PHX->RNO route, no recent news indicating active deployment, and no community sightings. Given the rollout status is 'rolling_out' but with zero equipped aircraft and no route-specific evidence, the probability remains anchored at zero. The fleet ratio does not serve as a floor here because the airline has not yet equipped any aircraft, and the rollout is not yet active.
