The jet is going to take over most of the routes. Of the Saab routes only SBP is going away, although I believe there will be some reduction in frequency on the other routes. However the jet is going to loose LAX-LAS, only American mainline will be flying that starting in Nov.
I've heard rumors of other cities opening up but nothing has ever come of it. Santa Fe was supposed to have happened a long time ago, but I think the city won't allow jets in that airport. I'd love to see cities actually ADDED to the L.A. system, they've done nothing but take away cities since long before I started working here.
LAX is going VERY senior with the Saab going away. Before the cuts I think it was 2 years to hold a line on the jet, but when the displacements finally get sorted out I think the most junior FO to even HOLD LA will be a late '06 early '07 DOH. I can only guess what the most junior line holder will be. I don't know the DOH on the most junior CA but I'm sure it's very senior.
The flying out of LA does get old after a while, but it is pretty and the weather is almost always good. Like Flyby1206 said those of us that are here live in California and really don't want to go anywhere else.
