Fleet
This section is an excerpt from Delta Air Lines fleet.[edit]

International Airport.
As of May 2024, the Delta Air Lines fleet consists of 989 mainline aircraft, making it the largest
commercial airline fleet in the world.[58][59][60] Delta Air Lines operates a fleet manufactured
by Airbus and Boeing.[61]
Delta operates the world's largest fleets of the Airbus A220, Boeing 717, and Boeing 757, the largest
passenger fleet of the Boeing 767, and the largest Airbus A330 fleet of any US airline.
Delta has historically preferred purchasing or leasing used aircraft or using older-generation models
to keep initial acquisition costs down. To support this business model, Delta has also invested in an
extensive MRO (maintenance, repair, and overhaul) organization called TechOps. However, Delta
has acquired lower-priced newer aircraft via discounts on slower-selling models and as aircraft
manufacturers transition to newer designs. As a result, as of 2023, Delta flies the second-oldest fleet
among the legacy carriers, and the average fleet age has been reduced to 15.3 years.[62][63]
Before its 2008 merger with Northwest Airlines, Delta's fleet was made up of solely American
manufacturers aircraft (except Airbus A310, which was acquired by collapsed Pan American World
Airways). Overseas manufacturers aircraft like Airbus from Northwest joined the fleet after the
merger, and more have since been added.
Cabin
Delta underwent a cabin branding upgrade in 2015.[64] Availability and exact details vary by route and
aircraft type.
Delta One
Delta One Suite
Delta One is the airline's premier business class product, available on long-haul international flights,
as well as transcontinental service from New York–Kennedy to Los Angeles and San Francisco.[64]
Delta One features lie-flat seating on all aircraft types, and direct aisle access from every seat on all
types except the Boeing 757-200 (in which only a special sub-fleet of approximately 20 aircraft
feature lie-flats).[65] The Boeing 767-300ER seats, designed by James Thompson, feature a space-
saving design whereby the seats are staggered such that when in the fully flat position, the foot of
each bed extends under the armrests of the seat in front of it. On the Airbus A330 cabins, Delta One
features the Cirrus flat-bed sleeper suite by Zodiac Seats U.S., configured in a reverse herringbone
pattern.[66]
All seats are also equipped with a personal, on demand in-flight-entertainment (IFE) system,
universal power-ports, a movable reading light, and a folding work table. Passengers also receive
meals, alcoholic beverages, an amenity kit, bedding, and pre-flight Delta Sky Club access. [67]
In August 2016, Delta announced the introduction of Delta One Suites on select widebody fleets.
The suites will feature a door to the aisle for enhanced privacy, as well as improved storage space, a
larger IFE screen, and updated design. The suites rolled out on the Airbus A350 fleet, first delivered
in July 2017, followed by installation within the Boeing 777 fleet.[68][69] Delta's Airbus A330-900, which
began revenue service for the airline in July 2019, also features Delta One Suites. [70] Also in July
2019, Delta began retrofitting a new seat on the 767-400ER, which featured increased privacy and
design similar to Delta One Suites, though without a privacy door.[71] These seats lack a door due to
the 767's smaller cabin width.
