Business Class Suites: 7 Airlines With Closing Doors In 2026

The new feature in business class that high-end passengers are craving is sliding doors. First introduced over a decade ago, they let customers essentially shut themselves off from the rest of the cabin, and any airline offering a top business class seat generally needs to offer privacy doors today. It has become increasingly popular, but some airlines offer more suites with doors across their fleets than others.

JetBlue was the first airline to offer sliding doors in business class, present on four out of the 16 seats in the carrier's original 2014 Mint cabin. Qatar Airways was the first airline to offer sliding doors at every seat with its QSuite in 2017, while Delta did the same later that same year with its Delta One Suite. Today, in 2026, these are the seven airlines operating the most aircraft equipped with business class suite doors.

7 Lufthansa

28 aircraft equipped with Allegris

The Lufthansa Allegris project involves a full nose-to-tail update of the airline's widebody interiors for all cabins. In business class, this includes a custom direct-aisle-access seat based on the Safran Optima IP, supplied by Stelia Aerospace, Collins Aerospace, or Thompson Aero Seating, depending on the aircraft type. Allegris is now available on 28 Lufthansa aircraft, split between ten Airbus A350-900s and 18 Boeing 787-9s.

One of the defining characteristics of the Allegris business class is that Lufthansa offers five different types of seats. However, only one of them, the front-row 'Suite', offers sliding doors, plus higher privacy partitions and significantly more personal space. It's among the best business class seats in the world and is available on all Allegris aircraft, but these are the only seats in the cabin with doors.

All future Lufthansa A350 and 787 deliveries will come with Allegris, while Lufthansa will retrofit most of its current A350-900s with the interiors (a handful of A350s acquired second-hand will leave the fleet). In addition, the carrier will retrofit Allegris onto its 17 Boeing 747-8s.

6 China Eastern

28 aircraft equipped with business class suites

China Eastern mainly relies on the Airbus A330 for short-to-medium range flights, while the Boeing 777-300ER is its flagship aircraft type. Its best business class product, however, can be found on its A350-900s and 787-9s, which are equipped with the Thompson VantageXL. This staggered seat product offers sliding doors and was one of the first business-class seats to include them.

China Eastern Airlines operates 20 A350-900s and eight 787-9s, for a total of 28 aircraft. This is the same number as Lufthansa's current Allegris fleet, but China Eastern offers sliding doors at every seat, which bumps it up this list. However, the German flag carrier is actively taking more new widebodies, whereas China Eastern has no outstanding A350 or 787 orders as of the time of writing.

These same seats also appear on Shanghai Airlines' 787-9s, as it is a wholly owned subsidiary of China Eastern, and they also offer sliding doors. While the Thompson VantageXL has been around for a while, it remains a top choice for long-haul travel, making China Eastern a top choice for nonstop flights to or from China when this product is available.

5 KLM

32 aircraft equipped with business class suites

KLM is the smaller airline of the two within Air France-KLM Group, but it has still received thorough investments for its long-haul product. The A330s are equipped with older seats configured six-abreast in business class, but KLM's Boeing 777s and 787s feature reverse herringbone lie-flats that offer direct aisle access. In addition, the seats on the 777 are equipped with privacy doors.

KLM currently operates 15 777-200ERs and 16 777-300ERs, for a total of 31 777s. Both of these aircraft types are equipped with the Jamco Venture, which is also used on the airline's 787-10s. The Dreamliner version is slightly older and lacks privacy doors, which are installed on the version used on the 777s.

KLM is starting to take delivery of new A350-900s, one of which is now on property. These planes are equipped with the Stelia Opera WB, a product Air France also uses on its A350s. Similar to the Jamco seat, this reverse herringbone model offers sliding doors, bringing KLM's fleet of suite-equipped widebodies to 32 aircraft with more on the way.

4 Air France

45 aircraft equipped with business class suites

Just like its Dutch sister, Air France has invested in its long-haul cabins to offer a consistently excellent business class product. Apart from the A330s, of which there are only five, all of Air France's widebodies offer reverse herringbone seats with direct aisle access, although some aircraft feature different seat models.

In 2023, Air France unveiled its first retrofitted 777-300ER with its latest long-haul interiors, including the Safran Versa for business class. This is an improved reverse-herringbone seat offering more space, better ergonomics, updated technology, and a sliding door. Later that year, the airline began taking delivery of new A350-900s in a premium-heavy layout and equipped with the Stelia Opera WB, a very similar product. Its first 20 A350s have different interiors and layouts.

So far, Air France has taken delivery of 23 A350-900s with the Stelia Opera WB, while retrofitting 22 777-300ERs with the Safran Versa. Of these, 18 aircraft also feature the airline's new La Premiere seats, while the remaining four are configured in a three-class layout with 48 business class seats.

3 Delta Air Lines

81 aircraft equipped with Delta One Suites

While JetBlue was the first airline to install sliding doors in business class, Delta Air Lines was the first airline to announce doors at every seat with its Delta One Suites in August 2016. Qatar Airways announced QSuites later and launched the product earlier, making Delta the third airline to install doors in business class and the second to offer them at every seat.

The Delta One Suites are currently offered on 41 A350-900s and 39 A330-900s, for a total of 81 aircraft. These seats are based on the Thompson VantageXL, although the versions used on the A350 and A330 are slightly different. Compared to rivals American Airlines and United Airlines, Delta was ahead of the curve, as those airlines didn't begin offering business class suites with doors until 2024 and 2026, respectively. What's more, the airline has large backlogs of A330-900s and A350s, meaning that the Delta One Suites fleet will grow even more.

The airline plans to retrofit an updated version of the VantageXL onto its fleet of 11 A330-200s and 31 A330-300s, while future A330-900 deliveries will also feature the updated seat. Meanwhile, Delta will soon begin taking delivery of A350-1000s, which will feature the Thompson VantageNOVA. This new reverse-herringbone seat with sliding doors from Thompson Aero Seating is the company's latest and greatest product.

2 British Airways

97 aircraft equipped with Club Suites

British Airways revolutionized the business class market when it introduced its Club World seats in 2000, which were the first lie-flat business class seats. However, the airline then basically didn't replace these seats for nearly two decades. In 2019, however, the airline took delivery of its first A350-1000, which featured Club Suites, the airline's latest business class product.

British Airways selected the Collins Aerospace Elevation, a reverse herringbone seat with a sliding door. This is not the primary business class seat offered by the carrier, and it's now available on all 18 of the airline's A350-1000s, all Heathrow-based 777s, all 787-8s, all 787-10s, and seven out of the carrier's 18 787-9s. The 787s are actively being retrofitted, while its Gatwick-based 777-200ERs with the old Club World seats will eventually be replaced by new 787-10s.

The major omission is the airline's Airbus A380 fleet, as all 12 of these planes still feature the old Club World seats. However, British Airways has begun its interior refurbishment program for the A380, which will include an updated version of the Elevation for Club Suites, along with new World Traveller, World Traveller Plus, and First seats.

1 Qatar Airways

119 aircraft equipped with business class suites

Qatar Airways was the first airline to offer sliding doors at every seat in business class with its 2017 QSuites, which remain maybe the best business class seat model in the world. The airline now offers this on 90 aircraft: 15 A350-900s (out of 34), all 30 A350-1000s, five of six 777-200LRs, and 40 of 57 777-300ERs.

In addition to the QSuites planes, Qatar Airways also operates 29 787-9s with a different type of enclosed suite. These aircraft are equipped with the Elevate Ascent, which is a reverse herringbone seat with sliding doors designed specifically for the 787. Within the airline's fleet, the A350-1000 and 787-9 are the only types where all aircraft feature suites with doors.

Qatar Airways is planning to introduce QSuites Next Gen in 2027. This product, first unveiled in 2024, was originally meant to launch on the Boeing 777-9, but delays to the 777X program mean that this product is likely to debut on the A350-1000 instead. The carrier has 12 A350-1000s still on order, along with 90 777-9s. Meanwhile, Qatar Airways is likely to install the Elevate Ascent on all future 787-9 and 787-10 deliveries.
