Airlines are struggling to get new planes delivered on time because the companies that make airplane seats are in a bind. After the pandemic, demand for custom, high-end seats has surged, but the industry is too spread out and bogged down by certification delays to keep up. Basically, everyone wants fancier seats, but the system isn’t built to handle the rush.

Editor’s Note: If you’ve noticed flight prices creeping up or fewer new planes on the tarmac, this is part of the reason. Airlines can’t expand or replace aging fleets fast enough, which could mean more crowded flights and higher costs for travelers. It’s another ripple effect of post-pandemic chaos in global supply chains—only this time, it’s hitting you at 30,000 feet.
