$1,225,000 (1945) Developed from Variants The Boeing 377 Stratocruiser was a large long-range developed from the military transport, itself a derivative of the. The Stratocruiser's first flight was on July 8, 1947. Its design was advanced for its day; its innovative features included two passenger decks and a, a relatively new feature on transport aircraft. It could carry up to 100 passengers on the main deck plus 14 in the lower deck lounge; typical seating was for 63 or 84 passengers or 28 berthed and five seated passengers.

The Stratocruiser was larger than the and and cost more to buy and operate. Its reliability was poor, chiefly due to problems with the four 28-cylinder and structural and control problems with their propellers. Only 55 Model 377s were built for airlines, along with the single prototype. Berths and seating aboard a 377 The Boeing 377 Stratocruiser was a civil derivative of the Boeing Model 367, the, which first flew in late 1944., who had become President of The Boeing Company in September 1945, sought to introduce a new civilian aircraft to replace reduced military production after. Boeing saw in their large-bodied, fast, and long-ranged military transport potential for a passenger aircraft suited for premium service on long transoceanic routes, expanding on the precedent set by their with.

Despite a recession in late 1945, Allen ordered 50 Stratocruisers, spending capital on the project without an order from an airline customer. His gamble that customers would be interested in Boeing's unique and expensive new airplane turned out to be correct for a brief period. On November 29, 1945 (Pan Am) became the launch customer with the largest commercial aircraft order in history, a $24,500,000 order for 20 Stratocruisers. Earlier in 1945 a had flown from Seattle to Washington, D.C. Nonstop in six hours and four minutes; with this knowledge, and with Pan Am President 's high regard for Boeing after their success with the, Pan Am was confident in ordering the expensive plane. The 377 shared the distinctive design of the C-97, with a 'double-bubble' fuselage cross-section, resembling a figure-8, with 6,600 ft³ (187 m³) of interior space, allowing for pressurization of a large cabin with two passenger decks.

Outside diameter of the upper lobe was 132 inches, compared to 125 inches for the DC-6 and other Douglas types (and 148 inches for today's 737). The lower deck served as a lounge, seating 14.

The 377 had innovations such as higher cabin pressure and air conditioning; the superchargers on the four Pratt & Whitney R-4360 engines increased power at altitude and allowed constant cabin pressure. The wing was the Boeing 117 airfoil, regarded as the 'fastest wing of its time'. In all, 4,000,000 man-hours went into the engineering of the 377. It was also one of but a few double deck airliners, another being its French contemporary, the, as well as Boeing's own and the. A total of 56 were built, one prototype (later reconditioned) and 55 production aircraft. First flight of the 377 was on July 8, 1947, two years after the first commercial order. The flight test fleet of three 377s underwent 250,000 mi (217,000 nmi; 402,000 km) of flying to test its limits before certification.
