OBJECT SHOWCASE: Contract
Airmail Routes (CAMs)
The original contract airmail routes, commonly
known as CAMs, were determined by postal officials and let
to bidders. 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). Contracted airmail service proceeded slowly
over the next couple of years. The U.S. Air Mail Service retained
control of the transcontinental New York – San Francisco
route making its last flight on that route September 9, 1927.
The Museum has a wide selection of CAM covers
in its collection.
