TWA (Transworld Airlines) was formed in 1930 with the merger of Transcontinental Air Transport and Western Air Express. Transcontinental Air Transport was known for its 1927 51-hour combined plane (daytime) and train (night time) trips across the United States.

In 1931, the company asked Douglas Aircraft to design planes to compete with Boeing’s 247D planes because United Airlines had claimed all of the planes from parent Boeing. In response to TWA’s request Douglas designed the DC-1 (1933) and DC-2 (1934).
