United Airlines has installed Starlink on over 300 regional aircraft and plans to equip more than 800 planes, representing a fleet coverage of 53.4%. However, there are no direct observations of Starlink on the SAN->LAX route, and the observation ratio is 0%. Recent news confirms Starlink use on mainline United flights but specifically on routes like Newark to Las Vegas, not SAN->LAX. Community sightings confirm regional fleet rollout completion but do not specify this route. Given the fleet coverage and rollout status, the probability is anchored below the fleet coverage ratio due to zero observations on this route, adjusted downward to 0.35 to reflect the lack of direct route evidence but supported by rollout and news context.
