After setting record-breaking 6½ hour transcontinental delivery flights, Delta promoted its DC-7 fleet as "America's Fastest and Finest Airliner."
Delta operated the world's first inter-continental DC-7 scheduled flight on April 1, 1955, with service from New Orleans to San Juan and Caracas.
Deluxe Douglas DC-7 aircraft carried passengers in all-first-class seating. The "luxurious interior" featured tan, turquoise and aqua fabric and leather accented in gold and silver. Gold window curtains depicted scenes along Delta's routes, "setting the mood for a Millionaire Dream Vacation in such gay holiday spots as New Orleans, Jamaica and Havana."
Golden Crown Service
Delta introduced DC-7 Golden Crown Service on February 1, 1956, with extra onboard amenities, including a typewriter for the workaholics and a shaver for the last-minute arrivals.
Delta launched industry-leading, luxury Royal Service with the Douglas DC-7 on September 22, 1958. Royal Service flights featured:
Delta received its first DC-7B on June 14, 1957.
The -7B model was slightly improved to allow either more range, with optional saddle fuel tanks in the engine nacelles, or more payload with increased gross weights. None of the 7B's U.S. operators, including Delta, installed the optional fuel tanks.
Of the 21 DC-7 aircraft that Delta flew, 10 were Model 7Bs. Delta originally ordered eleven DC-7Bs, but when the airline took delivery of Douglas' prototype DC-7B it was certified as a DC-7.
Delta retired its last Douglas DC-7B in 1967.
