United Airlines has a fleet coverage of 53.4% with Starlink installed on over 500 aircraft, including most of its regional fleet and some mainline aircraft. However, there are no direct observations of Starlink on the DAY -> IAD route, and the observation ratio is 0%. Recent news confirms Starlink is operational on some mainline flights but primarily on regional and select mainline aircraft, with no specific mention of this route. Given the lack of direct route observations and moderate fleet coverage, the probability is anchored conservatively below fleet coverage, adjusted downward to 0.40 to reflect uncertainty and no direct sightings on this route.
