The Boeing 80, sometimes called the Boeing Model 80 or just the Model 80, was an American airliner. It was a biplane with three engines. The Boeing 80 was built by the Boeing Airplane Company. It could carry mail and passengers.

Development and design

Boeing Air Transport was started on February 17, 1927 by William Boeing. On July 1, 1927, planes from Boeing Air Transport started flying mail from San Francisco to Chicago. At first, the Boeing Model 40A was used for this.

Boeing decided to make a plane to carry passengers. In 1928 it designed the Model 80. The Boeing 80 could carry 12 people. The pilots sat in a cockpit in front of the passengers.

The first Boeing 80 took off on July 27, 1928. Three more Boeing 80s were made before Boeing started to make the Boeing 80A. The Boeing 80A was longer and it could carry 18 people. It also had better engines. It first took off on July 18, 1929.


The Boeing 80 first flew for Boeing Air Transport on September 20, 1928. It soon turned out to be successful. The Boeing 80A started being used in September 1929.

In May 1930, Boeing Air Transport hired eight female flight attendants. They first flew on May 15. The Boeing 80 and 80A were used until the Boeing 247 replaced them in 1934.
