United Airlines has a moderate fleet coverage of 52.2% for Starlink-equipped aircraft, indicating a significant portion of their fleet is outfitted. However, there are no direct observations of Starlink on the PHL->SFO route, and no specific news or sightings confirm Starlink service on this route. Recent news confirms rollout and initial flights with Starlink on other routes, but none specifically mention PHL->SFO. Given the lack of direct route observations and the fleet coverage, the probability is anchored near the fleet coverage but slightly reduced to reflect uncertainty and absence of direct evidence for this route.
