United Airlines has installed Starlink on over 300 regional aircraft and plans to equip more than 800 planes by end of 2026, indicating a fleet coverage around 53.4%. However, there are no direct observations of Starlink on the IDA->DEN route, and recent news confirms Starlink primarily on regional and select mainline routes like EWR->LAS and the first Boeing 737-800 retrofit. Given the lack of route-specific observations and the fleet coverage ratio, the probability is anchored near the empirical observation rate (0.0) plus a conservative uplift reflecting fleet rollout and news evidence, resulting in a 0.40 estimate. This reflects moderate confidence that Starlink is available on this route but without direct confirmation.
