A starliner is a type of commercial spacecraft used primarily for the transportation of passengers. A significant portion of total interstellar travel within the United Empire of Earth (UEE) is done aboard these vessels. The Genesis starliner, manufactured by Crusader Industries and assembled in the upper atmosphere of Crusader (Stanton II), is one of the most common models of this type of ship. Major transportation companies such as Meridian Transit primarily operate starliners.
