manchester - san fransisco

Virgin announced a direct flight from Manchester to San Francisco starting next April. I have been checking prices and availability of reward seats waiting till our dates in June are on sale. There has been lots of availability for reward seats in both upper and premium. The direct flights now seemed to have disappeared and the only flights are via Atlanta or New York. There is now no availability for reward flights as they are not direct. Does anyone know if Virgin have cancelled this route.?
