British Airways has a fleet coverage of 50.5% with Starlink rollout currently in progress. Although there are zero confirmed Starlink observations on the JER->LHR route, the airline's rollout status and fleet coverage ratio set a floor for the probability at 0.505. Recent news confirms a full fleet-wide deployment commitment starting in 2026, supporting a probability anchored at fleet coverage. The lack of route-specific sightings and observations limits upward adjustment, so the probability is set equal to the fleet coverage ratio.
