All jobs on the PE and SP had run, or job, numbers. This is how the timekeepers would identify what you had worked. A lot of jobs had nick names, such as the one you are referring to, the Santa Monica AirLine job. It was simply called the "Airline" job. Even the crew dispatcher would call you and say simply "LV, you're called for the AirLine" or the "Huntington Beach" and so on. The job that switched the area around Beverly Hills was called the Culver Job. It was on duty 5 days a week at Sentous yard in Culver city. I would get called for the AirLine out of Butte St. and we would work the industries from Nevin siding (just after crossing the old 4 tracks at Amoco, outside of Butte St.) and continue on to Culver City to make a set out of cars for the Culver Job. We would pick up all of the traffic that the Culver job had for Butte St. as they did not go beyond Sentous yard towards Los Angeles. The AirLine job worked M-F, OD 0500.
As far as the jobs that switched the Bull Ring, Cornfield and River Station, I cannot comment on that as those were switchmen jobs and I was not a yardman.

Hope this helps you.
