United Airlines has a moderate fleet coverage of approximately 50.5% Starlink-equipped aircraft, indicating a significant rollout. However, there are no direct observations of Starlink on the DEN->SJO route, and recent news highlights initial Starlink flights primarily on other routes such as EWR->LAS and regional US routes. Given the lack of route-specific sightings and zero observed flights with Starlink on this route, the probability is anchored below the fleet coverage ratio, adjusted conservatively to 0.40 to reflect rollout progress and potential but unconfirmed presence on this route.
