Atlanta was an A350 route then swapped to 777 and has been one of a handful of routes attracting the ex-LGW trio of 777-200 which are currently without CS. They should have CS by next summer. As long as equipment remains 777 or reverts to A350 then CS will be guaranteed. If flying in the next 13 months then there will still be a chance of attracting a un-refurbished 777.
