Does the IAD–SFO route have Starlink?

Even on a high-coverage route, the actual aircraft assigned on the day of travel determines whether Starlink is on board. Search by specific flight number on StarlinkFlights for a per-flight confidence score.

Route-specific score for IAD–SFO

Why this score?

United Airlines is actively rolling out Starlink with over 52% fleet coverage, supported by high-confidence recent news confirming operational Starlink flights on mainline aircraft and regional fleet completion. However, there are no direct observations of Starlink on the IAD->SFO route, so the probability is anchored to the fleet coverage ratio of 52.2%. Given the lack of route-specific sightings but strong fleet-wide rollout evidence, a probability at the fleet coverage level is justified with a 'likely' confidence tier.
