In the 1980’s Air Cal had an interesting campaign using a piano man and highlighting the fact that you might just like their style. I do not think many airlines would do a commercial quite like this one today. Unfortunatly the colorful style of Air Cal did not make it past the 1980’s and in 1987, the airline was purchased by American Airlines.
Starting operations as Air California in 1967, they operated Lockheed Electra’s with a very classic looking livery and later operated the Boeing 737-200 in the same and then slightly modified livery.

AirCal also operated the 737-300.
