United Airlines has a fleet coverage of 53.4% with Starlink installed on over 300 regional aircraft and plans to equip more than 800 planes by end of 2026. However, there are no direct observations of Starlink on the GEG->SFO route, and recent news highlights initial mainline deployments primarily on other routes such as EWR->LAS. Given the lack of route-specific observations and the fleet coverage slightly above 50%, the probability is anchored conservatively below fleet coverage at 0.40, reflecting possible but unconfirmed presence on this route.
