Boeing · Airliner · Interwar (1919–1938)
The Boeing 80 was an American three-engine biplane airliner — Boeing's principal late-1920s commercial transport + the first US airliner to use stewardesses. Boeing designed the Model 80 in 1927-1928 specifically for Boeing Air Transport (Boeing's airline subsidiary, later merged into United Airlines) on the San Francisco-Chicago route; first flight 27 July 1928. About 16 Model 80s were built between 1928 and 1932. The aircraft served Boeing Air Transport + United Airlines on early US transcontinental routes 1928-1934.
The Model 80A (most-numerous variant) used 3 × Pratt & Whitney Hornet 9-cylinder radials (525 hp each). Maximum speed 217 km/h, range 740 km, service ceiling 4,265 m, MTOW 7,711 kg. Capacity: 12-18 passengers (depending on configuration). The aircraft introduced wicker seats with armrests, individual reading lights, lavatory, hot + cold running water, + cabin heating — standards for early luxury air travel. The all-metal corrugated-skin construction was unusual for biplanes of the era + offered better cabin sealing + durability than fabric-covered competitors.
The Boeing 80 is most-famous for inaugurating airline stewardesses — Ellen Church + 7 other registered-nurse 'Original Eight' were hired by Boeing Air Transport in May 1930 to staff Model 80 flights on the SFO-Cheyenne route. The stewardess innovation transformed airline customer service worldwide + Church became the first stewardess in commercial-aviation history. The Model 80 served Boeing Air Transport + United Airlines through 1934 before being retired in favour of the Boeing 247 monoplane. About 1 Model 80A survives in 2026 at the Museum of Flight, Seattle — restored to flying condition + occasionally flown for display.
The Boeing 80 was an old-style biplane airliner from 1928. It had three engines and two wings stacked on top of each other. The plane carried 12 to 18 passengers between Chicago and San Francisco. It was one of the first big airliners that Boeing ever made.
The Boeing 80 is famous for one big reason. It was the first American airliner to have stewardesses. A nurse named Ellen Church and seven other nurses became the first flight attendants in 1930. They served food, helped sick passengers, and made flying feel less scary for new travelers.
The plane was much smaller than a modern airliner. Its top speed was only about 135 mph. A Boeing 737 today flies almost five times faster. For the late 1920s, that felt thrilling. Passengers got wicker chairs, reading lights, hot and cold water, and even a small bathroom.
About 16 Boeing 80s were built between 1928 and 1932. They flew for Boeing Air Transport, which later became part of United Airlines. The plane stopped carrying passengers in 1934 when faster all-metal airliners took over the long routes across America.
The Boeing 80 could carry between 12 and 18 passengers, depending on how the seats were arranged. The plane also had two pilots up front and one stewardess to help passengers.
In the late 1920s, plane engines often broke during long flights. Three engines meant that if one stopped working, the plane could still fly safely on the other two. Modern jets use stronger engines, so they often only need two.
Ellen Church, a registered nurse + private pilot from Iowa, applied to Boeing Air Transport in early 1930 hoping to become an airline pilot. Boeing Air Transport's chief pilot Steve Stimpson rejected her pilot application but countered with a proposal for an in-flight nurse — passengers were often nauseated or ill on the unpressurised bumpy 1920s flights, + a trained medical caregiver would improve passenger experience. Church + 7 other nurses (the 'Original Eight') were hired May 1930 to staff Model 80 flights on the SFO-Cheyenne route. The 6-month trial proved enormously popular + Boeing extended the programme. Within 5 years every major US airline employed stewardesses; today the airline industry employs ~750,000 cabin crew worldwide, all descended from Church's pioneering work.
