Delta premium select vs delta one Delta Premium Select service is clearly preferable to basic economy, but it falls short of Delta One service. Delta Premium Select passengers are greeted with a welcome drink, and meals are served more elegantly than in economy. The dining service includes gourmet dishes, snacks, and beverages, as well as improved comforts like a pillow and blanket for extra comfort. Flight attendants give attentive service, but often with an emphasis on efficiency rather than customized care. Delta One's service is more personalized and tailored to each passenger's demands. Upon boarding, you are provided a pre-departure beverage, and meals are created by renowned chefs in partnership with high-end restaurants. The menu features multiple courses with fine dining options, including a variety of wines, cocktails, and other beverages. Service in Delta One is more personal, with attendants often checking in on passengers more frequently. On international flights, some flights even offer a mid-flight snack menu to enhance the overall dining experience.
