Like many airlines, JetBlue is currently trying to add more seats to some of its planes so it can accommodate more passengers per flight, and make more money for its bottom line. But there’s something standing in the way of JetBlue’s “cabin restyling program”: Broken toilets.

JetBlue is planning to reconfigure its A320 jets to add an additional 12 seats to the current 150. As part of that, the airline is installing Space Flex lavatories made by a company called Zodiac Aerospace. But in an earnings call this week, CEO Stephen J. Priest admits that the makeover hasn’t been perfect, citing “design challenges” with lavatories already installed on many of its restyled A321 planes.
