I know the A350 Suite is the flagship J product for Delta, and it was a wonderful seat, but when they close the curtain at the rear of D1, blocking off the PS galley, you're forced to get up and stretch in the very small and very utilized J galley up front. Makes me appreciate the VS 787 UC coffins since at least there you can get up and stretch at the bar or the open space (though in all honesty minus the lack of storage I love the ottoman for sleeping).
