Delta Air Lines is doubling down on premium travel, unveiling a redesigned business class suite and committing to one of its largest cabin upgrade investments, costing approximately $1 billion.
The airline announced it will introduce a next-generation Delta One suite on its incoming Airbus A350-1000 aircraft, expected to enter service in early 2027.
At the same time, Delta said it plans to retrofit its existing A330-200/300 fleet with suites featuring privacy doors for the first time, a significant upgrade for aircraft that previously lacked them.
Delta One suite features
The new Delta One suite, developed with Thompson Aero Seating over two years, is built around one central insight: improving passenger sleep. According to Delta, 97% of customers say the flat-bed seat is the main reason they choose the cabin.
So the airline made the suite three inches longer, giving travelers more than six and a half feet to stretch out.
After redefining premium travel, we’re raising the bar again – coming soon on our new A350-1000s. The only U.S. airline flying them.
This means:

A new pillow-top cushion sits over memory foam and pairs with Missoni bedding and a mattress pad to create a sleep experience that feels less like a plane and more like a bed.
The suite also comes with a 24-inch seatback screen, the largest Delta has ever installed. It supports Bluetooth for personal headphones and has wireless charging built into a stone inlay on the console. There’s a shoe cubby, a tray within arm’s reach of the bed for your phone, and even a hook for eyeglasses.
For the A330 fleet, many of the same features will carry over, including the pillow-top cushion, wireless charging, mood lighting, and privacy doors which is a first for the aircraft.
A snack bar at 30,000 feet
Another notable addition are self-serve snack stations for Delta One passengers. Located near the cabin entrance on the A350-1000 and at the front of the A330, the idea is to give travelers the freedom to grab something between meal services without flagging down a flight attendant.
It’s a simple addition, but Delta says it is part of a wider effort to put passengers in control of their flight experience.
Every seat gets an upgrade
The improvements are not just limited to business class. Delta Comfort+ and Main Cabin seats on both fleets will gain an extra inch of legroom and a new seatback shelf for personal items. Every seat across the aircraft will have memory foam cushions, USB-C and AC power outlets, and larger seatback screens with 4K resolution and Bluetooth capability.
The new in-flight entertainment system, built on technology from Thales that Delta first previewed at CES 2025, promises a deeper content library and personalized recommendations for SkyMiles members who sign in.
Cabin lighting has also been rethought, shifting from warm tones during meals to dimmer settings for sleep and a gradual brightening before landing to help passengers adjust to new time zones.
Accessibility improvements
Working with its Advisory Board on Disability & Accessible Travel, Delta has added new accessible features to both fleets. Seat controls now use tactile elements inspired by luxury cars, allowing adjustments by touch. Lavatories include similar tactile features, and each aircraft will have a dedicated accessible lavatory with more space for passengers with reduced mobility.
A focus on premium seats
Delta introduced the first all-suite business class cabin among US carriers back in 2017. It took four years before any competitor followed. Now, the airline says it operates more business class suites than any other US airline and expects 90% of its Delta One seats to feature sliding privacy doors by 2030.
The A350-1000, Delta’s largest aircraft yet, will have a 50% premium seat mix, an indication of where the airline sees demand heading.
Delta says its modern cabin design, first rolled out in early 2025, led to a 25-point jump in customer satisfaction scores. Over the next five years, the airline plans to bring that design to more than 800 aircraft through new deliveries and interior refreshes.
