United Airlines has hundreds of lie-flat business-class seats in storage with no immediate use, after ordering them years ago for Boeing 737 Max 10 aircraft that remain delayed. CEO Scott Kirby acknowledged the mismatch during an interview at Newark Liberty International Airport, saying the seats do not fit on other aircraft and the airline has not yet decided what to do with them.
The problem stems from United’s original plan to use the Max 10 on premium transcontinental flying, a role that has since shifted partly to specially configured Airbus A321neo aircraft. Those A321neos, branded for United’s Coastliner service, are now central to the airline’s narrowbody premium strategy, while the delayed Boeing programme has left bespoke cabin inventory stranded in storage.
The case underlines a practical cost of certification delays: cabin products built for one aircraft type are often too specialised to redeploy elsewhere. For United, that has complicated fleet planning as it balances premium demand, aircraft timing and the need to adapt its domestic long-haul network.
