AI Probability Analysis

Route-specific Starlink probability calculated from fleet data, live flight observations, news and community sightings.

Why this score?

Southwest Airlines currently has zero aircraft equipped with Starlink despite a high fleet coverage ratio of 86.2% reported for the overall fleet. The rollout status is 'rolling_out' with an announced start in summer 2026, and no confirmed Starlink observations or community sightings on the SJC->ONT route. Given the fleet is not yet equipped and no route-specific evidence exists, the probability is anchored at 0.0. The high fleet coverage figure likely reflects planned or future coverage rather than current reality. No recent news or sightings support a higher probability.
