They started in 1967 with Electras and quickly moved to 737's in 1968. I don't recall the Electras staying on non-TVL
flights, except to open up OAK
was all jet within 1968. Anyone else remember the original livery with the black nose?
-80's and BAe-146's came in after the 1981 name change and new AirCal livery. I don't recall the exact dates, but ~1984 seems plausible.
