The first DC-3 built was the Douglas Skysleeper Transport, and it was the height of luxury. Fourteen plush seats in four main compartments could be folded in pairs to form seven berths, while seven more folded down from the cabin ceiling. The plane could accommodate 14 overnight passengers or 28 for shorter daytime flights. The first was delivered to American Airlines in June 1936, followed two months later by the first standard 21-passenger DC-3.
