Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest data. Despite a high overall fleet coverage ratio of 86.2% reported, this figure does not reflect current reality since the rollout has not yet started and no flights on the TUL->MDW route have confirmed Starlink. No recent news or community sightings support a higher probability. Therefore, the probability is anchored at 0.0 reflecting the current lack of equipped aircraft and observations.
