CAM #18 San Francisco-Chicago

CAM #18 is the western portion of the Transcontinental Airway which was established on September 8, 1920 and followed a route from New York to San Francisco.  In 1927 the Transcontinental Airway was divided into 2 contract air mail routes, the western portion was known as CAM #18 and was awarded to Boeing Air Transport Inc., the eastern portion was known as CAM #17 and was awarded to National Air Transport.

At midnight June 31, 1927 the Post Office turned the operation of the western portion of the Transcontinental Airway over to Boeing Air Transport. 

CAM #18 has 3 airways, airways are referenced from west to east and south to north.  The western most portion of the airway's 1st beacon is given the number 1 and is usually 10 miles from the starting airport.  (each number represents a distance of approximately 10 air miles).

July 1, 1927 Boeing Air Transport will inaugurate its western section of the transcontinental mail service which it was awarded, in competitive bidding, by the Post Office Department. Mr. Boeing's ideas about the service, in brief, are:  "When we get this new commercial air mail service started to the Coast it will mean a great deal to Eastern and Western business men, as we not only will carry mail, but passengers and express as well.  Our schedule calls for the trip from San Francisco to Chicago in twenty-two hours, as compared with sixty-three hours by rail."

Twenty-five Planes, Each Carrying 1200 Pounds of Mail and Two Passengers, Begin Operation July 1,  Boeing Air Transport, Inc. was awarded the contract on the San Francisco to Chicago division of the transcontinental service, starting July 1, 1927, and continuing for a period of four years.  The operating Schedule will be the same as now maintained by the Post Office Department.
