Southwest Airlines is currently in the rollout phase for Starlink with a high fleet coverage expected by end-2026 but as of now, no aircraft are equipped and no confirmed Starlink observations exist on the TPA-PHL route. The fleet coverage is 86.2% projected but currently zero equipped, and no recent news or sightings support higher probability. Given rollout_status is 'rolling_out' and fleet_ratio is high but actual equipped count is zero, the probability must reflect current reality and not exceed observed data by more than 0.10. Therefore, the probability is anchored at 0.0 with low confidence in any Starlink availability on this route at this time.
