"The brand new Delta One seats don't have closing doors, but the product is still worth booking on a long-haul flight. Delta's recently established internal design team, Delta Flight Products, created the new Delta One entertainment screens in-house. The new lie-flat seats have memory foam cushions and convert to a completely flat bed. Privacy is a key upgrade in Delta One compared to the airline's other cabins with high, retractable dividers. The new Delta One cabin offers larger storage options with multiple expansive spaces."
