British Airways is currently rolling out Starlink with a very low fleet coverage of 1.9%, and no observed flights with confirmed Starlink on the SVQ->LGW route. The rollout is in early stages with only 5 equipped aircraft out of 261, and no community sightings or route-specific observations exist. Recent news confirms a fleet-wide deployment plan starting in 2026, but this route has no direct evidence yet. Given the low fleet ratio and zero observations, the probability is anchored to the fleet coverage ratio with a slight weight from rollout news.
