United Airlines has a fleet coverage of approximately 52.2% with Starlink equipped aircraft, indicating moderate availability. However, there are zero direct observations of Starlink on the EWR to PHX route, so empirical data does not support a high probability. Recent high-confidence news confirms that United has begun rolling out Starlink installations and specifically operated inaugural Starlink flights from Newark (EWR) to Las Vegas, a route close to PHX, suggesting growing deployment in the region. Regional fleet rollout is complete but less relevant for this mainline route. Given the lack of direct route observations but strong fleet and news evidence, the probability is anchored near the fleet ratio but slightly reduced to reflect no direct observations, resulting in a conservative estimate of 0.45.
