Revolutionary new jet design could solve flyers’ most annoying mid-air problem

The potty line is just plane better! A groundbreaking new jet design would fix some of flyers’ most irritating mid-air problems with special waiting rooms for bathrooms and four aisles to move more freely. Travelers — including weary parents with young kids — could avoid potential bathroom nightmares on JetZero’s spacious-but-windowless Z4 model, which is set to hit the runway as soon as 2030, according to the Wall Street Journal. The revolutionary sting ray-shaped plane is wider and flatter than ones currently flying commercially, creating a layout with bathroom waiting areas separated from passengers’ seats, according to the California-based start-up. The prototype allows flyers in line for restrooms more space to avoid bumping into passengers in seats or hovering awkwardly in the aisles
