The optimised cabin layout based on the ‘cabin enablers’ presented at Aircraft Interiors Expo (AIX), allows up to 80 additional seats* with no compromise on comfort: redesigned stairs (a ladder), a combined crew-rest compartment (you get to sleep conjoined to your steward), sidewall stowage removal (since PCs are verboten ), a new 9-abreast seat configuration in premium economy and 11-abreast (fat pax get two but must share knees if needed) in economy.
