The defining feature of this generation of business class is the door. Qatar started it with Qsuite, and now Delta One Suites, British Airways Club Suite, ANA The Room, JAL A350 suites, American's Flagship Suite and United's refreshed Polaris all close behind you. It photographs beautifully. Here is what it changes in practice.
Privacy from the aisle, mostly. Nobody brushes past your shoulder on the way to the lavatory, the galley light stops reaching your eyes, and on a day flight you can work without feeling watched. On crowded cabins it meaningfully lowers the noise of other people.
It does not make the seat longer, wider, or flatter. A recliner with a door is still a recliner. The seat underneath matters more than the wall around it: bed length, width at the shoulders, storage, and whether the seat faces the aisle or the window. Some of the best sleep in the sky is still on doorless products with excellent seats.
On overnight flights over about eight hours, and on airlines whose doored cabin is also a newer seat, the combination is usually worth a moderate premium. On flights under six hours, or where the doored option costs hundreds more for the same schedule, the money is often better spent on a better departure time. When two fares appear together on a route we show the aircraft on each, which is usually enough to tell which product you are getting.
