LAX bases
Skywest has bases in San Diego(E120), Carlsbad-Palomar(E120), Palm Springs (E120/CRJ), Fresno (E120), and I believe that LAX might only be a reserve base.
Express Jet is in the works to getting Ontario as a California base and Horizon is talking about getting LAX as a CRJ base.
Any pilots on here from the above mentioned companies please jump in and correct me if I have spoken incorrectly.
