What’s the Big Obsession With Doors?

February 3, 2026

Flying from Bangkok to Hong Kong the other day, I had the pleasure of sampling one of Cathay Pacific’s new “Aria” suites on the Boeing 777-300. This is Cathay’s swanky new business class product, currently available on a limited number of routes. A shame it was only a two-hour flight.

The food and wine were excellent — the service expedited for such a short ride. Find me a two-hour flight in the U.S. with a meal like the one below.

The “hard product,” to borrow industry parlance for the suite itself, was comfy and spacious. The layout is the common 1-2-1 herringbone, each seat with an oversized tray table and 24-inch video screen. (And I love the way Cathay’s headsets, while not bluetooth, are pre-plugged, with the attachment point hidden neatly away in a small amenities closet.)

What impressed me most, though, was the level of privacy. If you’re in the center section, as I was, a moveable panel closes you off from your neighbor, while on the aisle side your upper body sits deep within the sculpted shoulder wing.

It wasn’t until halfway through the flight that I realized there also was a sliding door. And I had to wonder, why bother? There was more than ample privacy as it was. With the seat in the bed position, there was barely two feet of open space, roughly at the position of your knees or mid-thigh. From Cathay’s point of view, is installing doors really worth the extra weight and mechanical complexity?

Looks like they’ve been bullied into it. For better or worse, doors are the industry standard these days. Indeed, airlines have gone sliding-door crazy. It’s become an arms race of sorts, and your first or biz class seat can’t be considered world class unless it comes with one, no matter how needless the amenity might be.

In some cases it makes sense. The geometry of a suite can be such that the lack of a door leaves you feeling exposed. The photo above, for example, shows the inside of an Emirates first class suite with its doors closed to the aisle (there are two that slide together). Without them, there’d be too much openness, too much clatter from outside.

But many are cozy enough to begin with, and the presence of a door feels gratuitous — even a little silly. They’re simply not needed.

If you insist, consider the way Air France does it, with a floor-to-ceiling curtain ensconcing each first class occupant. This is a simpler, less expensive, and much more elegant concept than the clunkiness of a door. (A curtain needs to be hung, however, which presents a problem for most cabin designs.)

How to define and quantify comfort? I reckon there are smarter ways for airlines to invest. We’re talking now about “soft product” enhancements, like better food or more gracious service. The worst thing a carrier can do is become hyper-focused on material aspects while the rest of its product deteriorates. I’d rather have a more attentive crew, a better meal presentation, or a less chaotic boarding experience, than some flimsy door.
