Travelers say Qatar Airways has the best business class, thanks to its QSuite with sliding doors and double beds: See inside

Qatar's narrowbody planes don't have QSuite, nor do its Boeing 787 Dreamliners or Airbus A380s, though the mammoth quad-jets have an inflight lounge and bar.

Without major changes, QSuite wouldn't fit on the narrower Dreamliners, so Qatar created a different version. The 787s sport a 1×2×1 business class with sliding doors and similar soft products but without the QSuite's versatility.

QSuite food is rated the region's best, and it won Skytrax's 2024 Best Business Class Onboard Catering in the Middle East award.

Qatar's business class is also staffed with specially-trained flight attendants, though the airline's entire crew earned praise this year for being named the best cabin crew in the Middle East by Skytrax.

This freedom has become the standard in airline business class, though a few outliers, like Air India and Germany's Lufthansa, still fly some cramped planes without direct aisle access.

The latter, however, has recently introduced a new and improved "Allegris" business class on its widebody planes.

In order, Singapore, All Nippon Airways, Emirates, and Cathay Pacific were the other top five winners behind Qatar.

Delta was number eight, while United was number 17. American didn't make the list.

The bed is created by combining two lie-flat seats into one, and closing both privacy doors creates a small pod — making it perfect for families and couples.

Singapore has refreshed its Airbus A380 business class with seats that combine into a double bed. It also offers double beds in its first-class suite, and Etihad Airways does in its three-room "The Residence."

Cabin designer Ameco was shortlisted for the Crystal Cabin Awards for its concept of a double bed — but as a sleep option for economy.

Qatar has several seating configurations.

Next to the window, there are front-facing and rear-facing single seats. The center section has double suites and four-person spaces, though they can also be used individually and blocked off by raising a middle divider.

The quad-seating is achieved by dropping the partition between two rear-facing and two front-facing center seats. It's good for families or colleagues traveling together who need to work, meet, dine, play games, or watch a movie together.

JetBlue Airways has offered a second seat in its Mint Suites for years, while Lufthansa, Virgin Atlantic Airways, and German leisure carrier Condor also offer the option.

Air New Zealand is adding a companion seat to its new Business Premier Suites cabin launching next year.

Doors revolutionized privacy. JetBlue Airways and Delta Air Lines were among the first to offer this feature when their Mint and Delta One suites launched in 2014 and 2017, respectively.

Delta is the only Big 3 airline to offer doors in business class, but American will join once its new door-equipped Flagship Suites debut later this year. United's Polaris business class remains door-free.

The list continues: Air India, Lufthansa, Virgin Atlantic, and Cathay Pacific Airways have added the perk.

Notably, five-star carriers Singapore and Emirates lack sliding doors in business but offer them in first-class suites.

According to Qatar's website, the QSuite flies nonstop to New York-JFK, Chicago O'Hare, Houston's George Bush Intercontinental Airport, Washington Dulles, Los Angeles, Dallas/Fort Worth, and Boston.
