The Boeing 80 was designed in response to increased demand on Boeing Air Transport’s San Francisco-Chicago route. The Model 80 carried passengers in a spacious cabin appointed with leather upholstery, reading lamps, forced-air ventilation, and hot and cold running water. The first version carried 12 people.

  • Model 80 – original production version with Pratt & Whitney Wasp engines (4 built)
  • Model 80A – improved aerodynamics and Pratt & Whitney Hornet engines (10 built)
  • Model 80A-1 – version with revised empennage; all 10 Model 80As converted to this standard
  • Model 80B-1 – single Model 80A built with open flight deck. Later modified to Model 80A-1 standard
  • Model 226 – one-off Model 80A converted to executive transport for Standard Oil. Modified tail surfaces later adopted on all Model 80As (see Model 80A-1)

The Boeing 80A introduced aviation’s first female flight attendants.
