General Characteristics and Role
The Boeing Model 80A-1 was a major milestone in the early history of American air transport. It was a large, three-engine biplane designed and built by the Boeing Company in the late 1920s specifically for carrying passengers and mail. The original Model 80 was Boeing’s first passenger airliner, but the upgraded 80A-1 featured more powerful engines and increased seating capacity, allowing it to carry 18 passengers—a significant number for the era. The aircraft was primarily operated by Boeing Air Transport (BAT), an early component of what would eventually become United Airlines, on routes along the U.S. West Coast and Rocky Mountains. Its enclosed cabin, lavatory, and presence of the first U.S. flight attendants marked a substantial improvement in passenger comfort.
