Southwest Airlines currently has a fleet coverage of 86.2% planned but has not yet equipped any aircraft with Starlink as of the latest data (May 2026). The rollout status is 'rolling_out' with no confirmed Starlink-equipped flights observed on the EUG->SJC route or any other route. No recent news or community sightings support higher probability. Given the announced rollout starting summer 2026 and zero current equipped aircraft, the probability remains at zero despite the high fleet coverage ratio, as the fleet coverage is prospective, not actual. Therefore, the probability is anchored at 0.0 with low confidence.
