British Airways is currently rolling out Starlink with a fleet coverage of 50.5%. Although there are zero observed flights with confirmed Starlink on the AGP->LGW route, the rollout status and fleet coverage set a floor probability of 0.505. No community sightings or route-specific observations exist, but recent news confirms a full fleet-wide deployment commitment starting in 2026. Given the medium confidence in rollout progress and lack of direct route observations, the probability is anchored at fleet coverage with moderate confidence.
