First Class is offered on all domestic aircraft, as well as Delta Connection aircraft with more than 50 seats. Seats range from 18.5 to 20.75 inches (47 to 52.7 cm) wide and have between 37 and 40 inches (94 and 100 cm) of pitch. Passengers aboard this class receive free snacks, drinks, and alcohol, with full meal service on flights 900 miles and longer. Certain aircraft also feature power-ports at each seat. When a domestically configured aircraft operates on an international route, such as those to the Caribbean, the first class cabin is branded as Business Class.

BusinessElite is Delta's international business class. Passengers in the BusinessElite cabin receive complimentary meals, refreshments, alcoholic beverages and an amenity kit. BusinessElite is also available on domestic transcontinental service between New York and Los Angeles or San Francisco.

Boeing 757-200 and certain Boeing 767-300ER aircraft configured with the BusinessElite cabin feature older recliner-style seating made by Recaro and BE Aerospace, respectively. BusinessElite seats on 767-300ERs have 60 inches (1,500 mm) of pitch and 18.5 inches (470 mm) of width, while seats on Boeing 757-200s have 55 inches (1,400 mm) of pitch and 20 inches (510 mm) of width. All seats are equipped with a personal, on demand In-Flight-Entertainment (IFE) system, universal power-ports, a movable reading light, and a folding work table. The BusinessElite seats ex-American Airlines/TWA 757-200s have electric recline, while those on ex-Northwest Airlines aircraft have mechanical recline. The ex-Northwest aircraft are planned to be converted back to a domestic configuration.

The flat-bed BusinessElite seats on 767-400ER aircraft (made by Contour Aerospace and designed by James Thompson) feature a space-saving design, with the bottom ends of the seats extending under the armrests of the suites in front when in the horizontal position.

Economy Comfort seats are installed on all Delta aircraft, as well as all two-cabin Delta Connection aircraft, and feature 38 inches (970 mm) of pitch; and on BusinessElite configured aircraft, 50 percent more recline over standard economy seats. Additional amenities include priority boarding, complimentary spirits on international flights, and HBO programming. Customers can upgrade from standard economy class seats to Economy Comfort seats. Economy Comfort more closely aligns Delta's offerings with its Transatlantic joint venture partners as KLM also offers an Economy Comfort section of its Economy cabin. Air France offers Premium Economy which is not the same as Economy Comfort.

Economy Class is available on all aircraft with seats ranging from 17 to 18 inches (43 to 46 cm) wide and 30 to 33 inches (76 to 84 cm) of pitch. The economy seats on Boeing 737, 747-400, 777, and selected Boeing 757-200, 767-300, and McDonnell Douglas MD-90 aircraft have an articulating seat bottom where the seat bottom moves forward in addition to the seat back tilting backwards when reclining.

Economy class passengers receive complimentary snacks and non-alcoholic drinks domestically. Alcoholic beverages are also available for purchase. Complimentary meals and alcoholic drinks are provided on long-haul international flights. As part of Delta's EATS buy on board program, food is available for purchase on all domestic flights 1,500 miles (2,400 km) or more (including Hawaii and Alaska flights, which no longer offer complimentary meal service).
