Why first-class seats are holding up new airplanes

Heated or cooled seats. Ultra-high-definition TV screens. Benches. Convertible beds. All-aisle access. And of course, the coveted privacy door.

Ever-more luxurious first- and business-class cabins that have hundreds of parts and require regulator approval are the latest hold-up as new airplanes arrive late to customers, according to the heads of the world’s biggest airplane manufacturers.

Boeing has 787 Dreamliners, a twin-aisle jetliner used on some of the world’s longest flights, on the ground at its South Carolina factory “that are held up for delivery for the seats, which obviously go in pretty late in the assembly process,” CEO Kelly Ortberg said at a Barclays industry conference on Feb. 20.

Part of the problem is airlines’ rush to win over high-paying customers by offering comforts and more of the scarce space on board — even if a few extra inches.

“It’s getting the seats certified, and it’s not actually the butt part of the seat,” Ortberg continued. “It’s the cabinet and the doors … for first class and business class. These are pretty complex systems, and getting those certified has taken both the seat suppliers and us longer than anticipated.”

Similar issues are hitting Boeing’s main rival Airbus, the CEO of the European manufacturer, Guillaume Faury, said on an earnings call the same day.

“We have delays in seats” as well as cabin “monuments” like galleys and closets that are “delaying the time at which we can deliver a plane fully completed,” Faury said.

Together the companies account for the vast majority of the commercial airplane market.

Aircraft deliveries are crucial for manufacturers’ revenue because customers pay the bulk of a jetliner’s price when they receive the plane, rather than when they first order it.

Some new aircraft cabins are still awaiting certification, and delays are adding to years of supply chain strains and labor shortages coming out of the pandemic.

In recent weeks, the Trump administration has fired hundreds of Federal Aviation Administration workers in a cost-cutting spree. The agency said the positions aren’t “safety critical,” but didn’t say whether staffing issues could further slow down aircraft or other certifications.

Getting the state-of-the-art seats installed at the front of the cabin means millions in revenue for airlines. For example, Delta Air Lines on Friday was selling a round-trip standard economy ticket between New York and Paris during the first week of May for $816. Move to…
