AirCal started out in 1967 as Air California, serving points in the Golden State from their base at Santa Ana Airport (now known as John Wayne Orange County Airport).

American Airlines bought out and absorbed AirCal in 1987.

Pacific Southwest Airlines was formed in 1949 and headquartered at Lindbergh Field in San Diego, California. Already known for frequent service, low fares, and few frills, PSA became a big player out West when Deregulation went into effect.

PSA, taking the piss from it’s competition. All airlines depicted would eventually be involved in mergers. PSA itself would be bought in 1988 by USAir (furthermore known as US Airways).
On another note, “five-across seating” was a standard feature in McDonnell-Douglas MD-80 aircraft, which was a common type used by PSA. The MD-80’s fuselage wasn’t wide enough to accommodate six-across seating like in Boeing narrowbodies.
