 | | The Air Mail Act, also known as the Kelly Act of February 2, 1925, recognized the leadership role of the postal service in the aviation field. |
 | | The act's purpose was to "encourage commercial aviation" by authorizing the Postmaster General to contract with airlines to carry mail. |
 | | The first five CAM routes were contracted in 1925 to Colonial Air Transport, Inc. (Boston to New York); Robertson Aircraft Corp. (Chicago to St. Louis); National Air Transport, Inc. (Chicago to Dallas); Western Air Express, Inc. (Salt Lake City to Los Angeles); and Walter T. Varney (Elko, Nevada, to Pasco, Washington). |
