Service Extends from Coast to Coast
Air mail service opened between New York and Chicago in September 1919. Service reached Omaha, Nebraska, the following May. In September 1920 it reached San Francisco.
Compared to moving the mail by train, flying cut coast-to-coast delivery time by about a day. When regular overnight air mail service began in 1924, it slashed delivery time to 29 hours-almost three days faster than by rail. |
