Here's a collection of images of the long lost Boeing 314 flying boat, the luxury skyliner that plied the skies in the 1930s and 1940s, and which came complete with sleeper bunks and formal dining:
The Passenger Compartment: The interior of the passenger cabin was the height of luxury for the time, and would surely impress today. In the lounge, travelers had room to spread out and play backgammon or put together puzzles. When it was meal time the lounge converted into a formal dining room, complete with fine china and five star service. When the evening arrived, all compartments converted into bunks with dark curtains and high quality sheets… perfect for dreaming of warm Pacific beaches.
