If you want to get based at LAX with Eagle, the SF3 is your only choice. As stated before, 2 yrs. seniority is required to hold ERJ out of LAX. SF3 LAX's seniority list is a little bit different. The bottom of the list is very junior for FO's, but the top half has some of the most senior FO's in the system. LAX for Skywest is, indeed, a CRJ reserve base only. One option that has not been brought up is that LAX is now a base for ASA, and I've been told people with about a year's seniority with the company can hold LAX. The flying out here is a lot of fun! Hope that helps!
