In 2017, Delta Air Lines introduced its Delta One Suite, which is the carrier’s latest business class product. At the time, Delta was the first global US carrier to add a door to a business class seat (JetBlue Mint also had doors at select seats, though JetBlue didn’t operate any long haul routes at the time).
It has now been around eight years since Delta introduced its new business class product, so how many of the carrier’s long haul jets have this product? I’d like to talk about that a bit in this post, so that passengers can get a sense of which product they’ll find on which Delta aircraft. I wrote similar guides for American and United.
What are Delta One Suites in business class like?
Delta refers to its latest business class product as Delta One Suites. This is a modified version of the Vantage XL seat, which you’ll find on a variety of airlines. Personally I rank this toward the bottom of the list of the world’s best business class seats (meaning it’s very good, but there are some better products).
These seats are pretty solid and they’re in a staggered configuration, with doors. Now, the seats may feel a bit tight for some people — one of the reasons these staggered configurations are so popular with airlines is because of how efficiently they utilize space, with the area for your feet being located to the side of the seat in front.
Anyway, it’s the best that the airline has to offer, so if you do fly Delta business class, you’ll ideally want to end up on these planes.
Which planes have Delta One Suites?
Given Delta’s huge and varied wide body and international fleet, on which aircraft can you expect to find Delta One Suites? Let’s take a look, covering all Delta aircraft that have flights that are marketed as Delta One (which is what Delta calls its premium business class).
All Airbus A350-900s have Delta One Suites
Delta currently has a fleet of 38 Airbus A350-900s, with another six of these jets on order (in addition to 20 Airbus A350-1000s, which will be delivered starting in 2027, and should feature a new business class product).
All Delta A350-900s have Delta One Suites. This is the aircraft for which the Delta One Suite was designed, and you’ll find that this aircraft also has the most spacious business class seats. While the seats are the same, note that there are two types of configurations — one has 32 business class seats, and the other has 40 business class seats.
All Delta A330-900neos have Delta One Suites
Delta currently has a fleet of 39 Airbus A330-900neos, with no more of these planes on order. All Delta A330-900neos have identical interiors, with Delta One Suites that have doors.
The catch is that given the A330-900neo’s narrower fuselage, you’ll find that the Delta One Suite feels quite a bit tighter than on the A350-900.
No Delta A330-200s & A330-300s have Delta One Suites
Delta has a fleet of 11 A330-200s and 31 A330-300s. These planes have reverse herringbone seats in business class. While this is a popular kind of seat, these are far from the most cutting edge reverse herringbone seats out there, and many find them to feel a bit tight.
Delta has plans to retrofit its A330-300s as of late 2026, though we don’t know what kind of a product they’ll get. My assumption would be that they’ll get Delta One Suites, similar to what you’ll find on the A330-900neo, but that’s purely speculation. Meanwhile there are no plans to reconfigure A330-200s. While I imagine they’ll fly well into the 2030s, they are a bit older than the A330-300s.
No Delta 767-400ERs have Delta One Suites
Delta has a fleet of 21 Boeing 767-400ERs, which are used for both international and key transcontinental routes. These planes have a staggered business class configuration, though at least it has been refreshed in recent years. While these planes don’t have Delta One Suites, they do have some privacy partitions, and updated finishes.
These seats will still feel on the tight side, given the narrow fuselage of the 767, plus how staggered seats are arranged. While the 767-400s have more modern seats than the A330-200s and A330-300s, I’d still say that the A330s offer a more comfortable seating configuration. Delta doesn’t have plans to update the interiors of the 767s further.
No Delta 767-300ERs have Delta One Suites
Delta has a fleet of 38 Boeing 767-300ERs. These planes are by far Delta’s weakest wide body jets, and I’d argue these have among the worst business class seats you’ll find on any carrier, at least compared to what you’d hope the airline offers.
These seats are tight, outdated, have small entertainment monitors, etc. What’s so frustrating is that these jets are flown on all kinds of transatlantic routes where Delta charges top dollar, while offering a disappointing experience. Delta has no plans to update these interiors, though the planes are expected to be pulled from international flights by 2028, and to be retired by 2030 (though who knows).
No Delta 757-200s have Delta One Suites
While not a wide body jet, some Delta 757-200s also have a Delta One cabin. Delta has 77 Boeing 757-200s, but only 12 of them have flat beds, and operate routes where the forward cabin is marketed as Delta One. On these planes, Delta has the Collins Aerospace Diamond product, which are fully flat seats in a 2-2 configuration. This isn’t an exciting product, but you really can’t expect much more for an outdated narrow body aircraft like this.
Bottom line
Back in 2017, Delta introduced its new Delta One Suites business class. So far, this product is found on all A350-900s and A330-900neos. Unfortunately you’ll find different seats on the carrier’s A330-200s, A330-300s, 767-300ERs, 767-400ERs, and 757-200s.
It’s disappointing that Delta has gone so many years without retrofitting the new suites on any other planes currently in service. The A330-300s should get some new seats starting in 2026, but that’s the extent of the plans to retrofit the existing fleet.
What do you make of the rollout of Delta One Suites?
