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 SJO->IAD route, and recent news confirms Starlink primarily on regional and select mainline routes such as EWR->LAS. Given the lack of route-specific observations and the fleet coverage ratio, the probability is anchored near the fleet coverage but slightly reduced to reflect no direct sightings on this route. The rollout is ongoing, and mainline installation is recent and limited, so a moderate probability with medium confidence is appropriate.
