Delta One, on the other hand, is a business-class offering created for travelers ready to pay a premium for luxury, privacy, and the best in-flight experience. Delta One flights can be significantly pricier than Premium Select fares, but the investment provides far more benefits, such as fully lie-flat beds, a personalized service experience, high-end amenities, and a variety of special perks. Delta One's services will appeal to both business travelers who need to be productive throughout their flight and luxury-seeking leisure visitors.
