Delta Air Lines is introducing a new generation of Delta One business class suites, with bigger beds, 24-inch entertainment screens, improved storage and more privacy. The new seats will debut on the Airbus A350-1000 in 2027, while the airline’s older A330 aircraft are also getting a substantial upgrade. Here’s what passengers can expect.
Delta was among the first airlines to introduce business class suites with sliding privacy doors, launching its original Delta One Suite in 2017. Nearly a decade later, the airline is preparing a new version for its largest long-haul aircraft.
The next-generation Delta One Suite has been developed with Thompson Aero Seating following two years of design work, drawing on feedback from passengers and cabin crew.
Delta is also bringing suites with sliding doors to its Airbus A330-200 and A330-300 aircraft for the first time. By 2030, the airline expects 90% of its Delta One seats to offer sliding privacy doors.
What’s new in Delta’s next-generation Delta One Suite?
The new A350-1000 suites retain the familiar 1-2-1 reverse-herringbone layout, giving every passenger direct aisle access.
Window seats face towards the aircraft windows, while the centre suites feature sliding privacy dividers. Passengers travelling together can open the divider to communicate more easily or close it for greater privacy.
Delta has paid particular attention to the details passengers use throughout a long flight.
The new suites include:
- A fully flat bed measuring more than 6½ feet, over three inches longer than the previous design.
- A pillow-top cushion layered over the memory foam seat.
- A 24-inch 4K QLED entertainment screen.
- Bluetooth connectivity for personal headphones.
- Wireless charging integrated into the console.
- USB-C and universal AC power outlets.
- Personal mood lighting and a distinctive reading lamp.
- Additional storage, including a dedicated space for shoes.
- Tactile seat controls inspired by luxury car interiors.
The improvements should make a difference to passengers who spend much of a long-haul flight sleeping, working or watching films.
A longer, more comfortable bed
One of the most welcome changes is the longer sleeping surface.
The new Delta One Suite converts into a fully flat bed measuring more than 6½ feet. That gives taller passengers a little more room to stretch out.
Delta has also added a pillow-top layer to the seat cushion, intended to improve comfort when passengers are lying down.
The extra padding complements the airline’s existing Delta One bedding, including its Missoni collection.
A larger entertainment screen and wireless charging
Every next-generation Delta One Suite on the A350-1000 will have a 24-inch 4K QLED screen, the largest Delta has installed in an aircraft seat.
The entertainment system supports Bluetooth, allowing passengers to connect compatible wireless headphones rather than relying on an airline headset or wired connection.
Wireless charging is built into the suite’s console, with additional USB-C and AC power connections available.
These are practical improvements for passengers who travel with several electronic devices.
Which Delta aircraft will have the new suites?
Three aircraft types are included in the announced programme, although the new A350-1000 suites and refurbished A330 suites will not be identical.
| Aircraft | Delta One upgrade | Timing |
|---|---|---|
| Airbus A350-1000 | New-generation suites with 24-inch screens and longer beds | From 2027 |
| Airbus A330-200 | Refurbished cabin with Delta One suites and privacy doors | Retrofit programme |
| Airbus A330-300 | Refurbished cabin with Delta One suites and privacy doors | Retrofit programme |
Delta’s A350-900 and A330-900neo aircraft already offer Delta One suites on many flights. However, these are existing designs, not the new A350-1000 product.
Passengers should check their aircraft type and seat map before booking, particularly while the A330 refurbishment programme is underway.
What will change on Delta’s A330-200 and A330-300?
Delta’s older A330 aircraft are receiving much more than replacement seat covers.
The airline is introducing Delta One suites with sliding privacy doors as part of a complete cabin refurbishment.
Many features from the new A350-1000 design will also appear on the A330s, including improved cushioning, wireless charging, tactile controls, personal lighting and updated storage.
Passengers in the other cabins will benefit too.
Delta is installing new entertainment systems with 4K QLED displays, Bluetooth connectivity and updated power connections throughout the aircraft. Memory foam seat cushions will also be fitted across all cabins.
Delta Comfort and Delta Main seats will receive a redesigned seat with an additional inch of legroom, according to the airline.
Are the new Delta One Suites accessible?
Delta consulted its Advisory Board on Disability & Accessible Travel when developing the new cabins.
The airline has designed tactile seat controls that passengers can operate by touch, rather than relying entirely on touchscreen menus.
Tactile features will also be incorporated into the lavatories, and both the A350-1000 and refurbished A330 aircraft will have a dedicated accessible lavatory with additional space for passengers with reduced mobility.
These changes are particularly relevant to travellers who may find conventional airline seat controls difficult to use.
Passengers requiring assistance should still contact Delta before travelling to confirm the accessibility arrangements for their particular flight.
Will Delta One passengers get new dining and amenities?
Yes. Delta has also announced a wider refresh of its Delta One experience, including changes to meals, beverages, bedding and onboard service.
The new Delta One hospitality programme is being introduced on flights departing Los Angeles in autumn 2026, with a wider rollout planned for 2027.
The airline is also adding self-service refreshment stations to the A350-1000 and refurbished A330 aircraft, allowing Delta One passengers to collect snacks between meal services.
The A350-1000 station will be located near the main aircraft entrance, while the A330 version will be at the front of the aircraft.

When can passengers fly in the new Delta One Suite?
Delta expects its first Airbus A350-1000 aircraft to arrive in early 2027.
The airline has ordered 20 A350-1000s, which will be used on long-haul international and hub-to-hub services.
The aircraft will have a particularly high proportion of premium seats, with Delta One, Delta Premium Select and Delta Comfort accounting for approximately half the cabin.
However, Delta has not yet confirmed the first commercial route for the new A350-1000 suites.
The A330 refurbishment programme is also underway, but passengers should not assume every A330-200 or A330-300 will have the new cabins immediately.
As aircraft are refurbished and new A350-1000s enter service, checking the seat map will be the most reliable way to identify the available Delta One product.
Frequently asked questions about Delta One Suites
Do all Delta One seats have privacy doors?
No. Delta One is the airline’s long-haul business class product, but the seat design varies by aircraft. Some aircraft offer enclosed suites, while others have lie-flat seats without doors. Delta expects 90% of its Delta One seats to have privacy doors by 2030.
How long is the bed in the new Delta One Suite?
The A350-1000 suite converts into a fully flat bed measuring more than 6½ feet, over three inches longer than the previous design.
Can couples sit together in Delta One Suites?
Yes. The new A350-1000 cabin has centre suites with adjustable privacy dividers. Passengers can open the divider to communicate or close it for privacy. The seats remain separate individual suites.
Does the new Delta One Suite have Bluetooth?
Yes. The new entertainment system supports Bluetooth connections to compatible personal headphones.
Which Delta aircraft has the best Delta One Suite?
The A350-1000 will introduce Delta’s newest suite design in 2027, including longer beds and larger entertainment screens. Until passengers have flown in the new cabin, it is too early to judge whether it is more comfortable than every existing Delta One configuration.
Is the new Delta One Suite available to book?
The next-generation A350-1000 suite is scheduled to enter service in 2027. Passengers will need to wait for Delta to confirm the aircraft’s routes and operating schedules before identifying specific flights with the new cabin.
