Pacific Airlines increased
its jet system by adding Boeing 727 flights out of Las Vegas on April 30, 1967.
This cover was carried on the inaugural Air Mail Route 76 Jet flight from Las Vegas, Nevada to San Jose, California (where it was backstamped) and is listed in the Jet Age Flights section of The American Air Mail Catalogue as J-1317.
The Civil Aeronautics Board and President Lyndon Johnson approved the simultaneous merger of three airlines for the first time in early 1968. Pacific Air Lines, Bonanza Airlines, and West Coast Airlines were combined to form Air West. Air West provided service to eight Western states, Canada, and Mexico within its 8,800-mile system.
