United Airlines has installed Starlink on over 300 regional aircraft and is rolling out to reach over 800 planes, representing about 53.4% fleet coverage. However, there are no direct observations of Starlink on the ONT-ORD route, and the observed rate is 0%. Recent news confirms Starlink is active on mainline United flights but primarily on routes like EWR-LAS and regional US routes. Given the fleet coverage and rollout status, the probability is anchored near the fleet coverage but adjusted downward due to zero direct observations on this route. The probability is conservatively set at 0.40, slightly below fleet coverage to reflect uncertainty and lack of direct route evidence.
