Delta One is Delta Air Lines’ flagship business class cabin, offering a more comfortable and convenient way to fly long-haul. With lie-flat seats, upgraded dining, and an improved airport experience, Delta One is designed to make every part of the journey feel smoother and more enjoyable.

Passengers also benefit from a more personalized service, priority boarding, and enhanced inflight entertainment options. Let’s take a closer look at Delta One, the aircraft equipped with the product, and some of the key benefits passengers can enjoy when traveling in the SkyTeam member’s flagship business class cabin.

What Is Delta One?

Delta One replaced Delta Air Lines’ former business class offering (known as BusinessElite) in 2014, and is today the carrier’s flagship business class product. The most recent iteration of the Delta One cabin was launched in 2017, when the carrier took delivery of its first Airbus A350-900 aircraft. Delta One has since gone on to become one of the most recognizable long-haul business class products offered by a US carrier, and while the overall experience can differ slightly depending on the aircraft type, Delta One focuses on comfort, privacy, and elevated service.

Delta One Suites is the newest and most advanced version of Delta One, and is found onboard the Delta Air Lines’ most modern aircraft – the Airbus A330-900 and A350-900. These aircraft feature fully enclosed suites with sliding doors, lie-flat beds, direct aisle access, and a 1-2-1 layout that prioritizes personal space. The design emphasizes privacy and contemporary styling, giving the cabin a competitive edge, while storage areas, intuitive seat controls, and large entertainment screens all contribute to an industry-leading passenger experience.

However, Delta Air Lines’ long-haul network is operated by a diverse fleet, and so not every Delta One cabin looks the same. The airline has retrofitted its Boeing 767-300ERs, 767-400ERs, and even some 757-200s with its Delta One product. Although Delta One on these older aircraft still offers fully flat beds and upgraded amenities, it does not feature sliding doors and therefore cannot be considered suites in the same sense as Delta One found on the carrier’s newer Airbus A330-900 and A350-900 aircraft.

However, regardless of aircraft type, Delta One passengers can expect an elevated end-to-end experience. This includes premium check-in options, priority security, dedicated lounge access, a curated onboard service featuring regionally inspired meals and a rotating selection of wines and spirits, and a luxury amenity kit. With ongoing investments in its fleet and cabin products, Delta Air Lines continues to position Delta One as a central pillar of its long-haul strategy, aiming to offer a consistent and competitive premium experience across its global network.

Which Aircraft Feature Delta One Suites?

Delta Air Lines’ flagship Delta One Suites are found onboard the carrier’s Airbus A330-900s and A350-900s. The A330‑900neo is a newer version of the A330, with improved engines and aerodynamics. The aircraft’s first flight was in October 2017, and Delta Air Lines took delivery of its first example in May 2019. The aircraft offers increased fuel efficiency and passenger comfort compared to older A330 models, and it is used on medium- and long-haul international routes.

Meanwhile, the Airbus A350‑900 first flew in June 2013, and Delta Air Lines received its first aircraft in July 2017, making it the first US airline to operate this model. The aircraft is used primarily on long-haul international flights due to its fuel-efficient design and extended range. Both the A350-900 and A330-900 represent Delta Air Lines’ commitment to modernizing its fleet with fuel-efficient, technologically advanced airplanes.

Delta One Suites can therefore be found on routes operated by Delta Air Lines’ Airbus A330-900s and A350-900s, including many transatlantic and transpacific services. This includes the carrier’s recently resumed service between its megahub at Hartsfield-Jackson Atlanta International Airport (ATL) and Accra Kotoka International Airport (ACC) in Ghana.

Delta One Lounge Access

Before they board their flight, Delta One passengers have access to Delta Air Lines’ newest premium ground experience – the Delta One Lounge. The SkyTeam carrier has four Delta One Lounges conveniently located at four of its major international gateways – New York John F. Kennedy International Airport (JFK), Los Angeles International Airport (LAX), Boston Logan International Airport (BOS), and Seattle-Tacoma International Airport (SEA). These lounges represent a major step forward in Delta Air Lines’ effort to compete with the top global carriers when it comes to end-to-end premium travel.

Each Delta One Lounge is built around the idea of offering a calm, refined environment that complements the inflight experience. The spaces are noticeably more upscale than the already well-regarded Delta Sky Clubs, featuring elegant interior design, quieter seating zones, and enhanced privacy. Delta Air Lines leans heavily into a hospitality-focused approach, with staff trained to provide more personalized service from the moment passengers arrive.

Food and beverage offerings are one of the standout features of the Delta One Lounge experience. Menus are curated by renowned chefs and updated seasonally, while the bars serve a selection of premium wines, cocktails, and spirits carefully chosen to complement the lounges. The lounges also include spa-inspired showers, dedicated relaxation zones, private workspaces, and high-end design touches that showcase local influences.

By positioning Delta One Lounges at major coastal hubs (New York John F. Kennedy International Airport for transatlantic service, Los Angeles International Airport and Seattle-Tacoma International Airport for transpacific routes, and Boston Logan International Airport for both), Delta Air Lines ensures its premium passengers begin their journey with a consistent, elevated ground experience. At airports without a dedicated Delta One Lounge, Delta One passengers can use the Delta Sky Club.

Chef-Curated Meals

Just like in the Delta One Lounge, Chef-curated meals are a central part of the Delta One experience onboard, reflecting Delta Air Lines’ push to offer restaurant-quality dining at 35,000 ft. The airline partners with a rotating lineup of acclaimed chefs and regional culinary teams to develop menus that highlight fresh, seasonal ingredients while capturing local flavors from the regions Delta Air Lines serves.

This approach ensures that the onboard dining feels thoughtful and contemporary rather than generic airline fare. Each multi-course meal service typically begins with a plated appetizer and a fresh salad, followed by a choice of entrées designed specifically for the in-flight environment.

Because taste perception changes at altitude, Delta Air Lines’ chefs focus on bold flavors and balanced seasoning that work well in the air. Complementing the food is a carefully selected wine program, featuring bottles chosen in partnership with expert sommeliers.

The Additional Benefits Of Flying Delta One

Flying Delta One comes with several additional benefits that enhance the entire travel experience, beginning well before passengers step onto the aircraft. The airport journey is noticeably smoother thanks to dedicated Delta One check-in counters, which are quieter and more efficient, allowing passengers to move through the airport with far less stress than the standard check-in environment. In many locations, Delta One passengers also enjoy expedited security access, helping them bypass long lines and reach the lounge and gate area more quickly.

Priority boarding completes the ground experience, ensuring Delta One passengers are among the first to settle into their seats and get comfortable. Once onboard, connectivity is a standout advantage, with Delta Air Lines offering free high-speed Wi-Fi for Delta One passengers. Combined with large seatback screens and an extensive content library, the cabin environment supports both work and relaxation.

Baggage allowance is another key benefit, as Delta One passengers can check two bags at no additional cost, typically with higher weight limits than those permitted in the main cabin. Priority baggage handling also means that checked luggage is among the first to arrive at the carousel after landing, reducing waiting time and helping passengers move efficiently from airport to destination.

Delta Air Lines’ Wider Fleet

Although not all of Delta Air Lines’ aircraft feature Delta One, it is worth taking a look at the carrier’s fleet, given that it is one of the largest and most varied in the world. The latest data from ch-aviation shows that Delta Air Lines currently operates a total of 986 aircraft, including some of the last remaining commercial Boeing 717s, with a further 261 aircraft on order. The aircraft types found in the SkyTeam carrier’s fleet are outlined in the table below:

As we can see, Delta One is a product primarily available across the airline’s widebody fleet, with the exception of a select number of its narrowbody 757-200 fleet. While yet to be officially confirmed, Delta is planning a new Delta One suite onboard its A350-1000s.
