Abstract: An airline service tray assembly includes a service tray having a top surface and a bottom surface and brackets adapted to allow the service tray to move between an upright position wherein the top and bottom surfaces generally vertical and a down position wherein the top and bottom surfaces are generally horizontal. The service tray has a cavity sized and shaped for receiving an advertisement sheet therein and is adapted such that the advertisement sheet located within the cavity is at least partially viewable from the exterior of the service of the service tray. The cavity is preferably provided with a window through which the advertising sheet within the cavity can be at least partially viewed. The window is preferably located at the bottom surface so that the advertising sheet can be at least partially viewed when the service tray is in the upright position.
