Where a few people complain that they dislike these planes, I'm a fan given how large the leg room is vs. other Delta One products on planes like the 767s, A330s and A340s. Though they are not as nice as the standard Delta A350s, they are superior to many other products and I won't complain very loudly. You also benefit from using Global Upgrades directly from Comfort vs. Premium Select. Enjoy.
This flight in question was not on an ex-LATAM 350. DL has never flown A340's.
Rechecking this flight, appears that DL has finalized the A333 for this route and is now selling PS seats with D1 available at booking for a GUC from paid PS. So OP can hopefully act accordingly.
