but for the most part, all these ticket services are the same... i never buy from them directly... i just use their service to search for airfare, then go directly to the airline's website to buy the ticket (save a few extra bucks doing that)...
also, did you try airlines that only sell through their own website, ie southwest?... or you could maybe get a cheap ticket on jetblue, though they fly into long beach... all depends how far you'll go to save money (though if you go too far, that might cost you more money becuase of the time wasted in commute)...
ill be in LA this weekend too... got a ticket on aloha airlines for $100 roundtrip from sacramento to orange county. it would cost me more in gas money to drive it and luckily i have friends to help me out while im down there.
