Passenger seat armrests and consoles have laterally translating armrest doors that open and close to allow for deployment and stowage of tray tables. The armrest doors may be guided through their translation by slides or a linkage that controls their motion. The armrest doors may also translate in two-dimensions, incorporating a vertical translation as well as a lateral translation. The resulting motion allows for better placement of the deployable tray tables within the armrest or console and a reduction in wasted space. The passenger seat armrests may also incorporate cocktail trays that can be integrated into the armrest doors or the armrest or console itself.
