Southwest flies into Burbank, Ontario, LAX, and Long Beach in the LA area. You can check out all of their schedules depending on where you will be.
The "Hollywood" & "LA" scene isn't like what you are thinking. Los Angeles isn't all glitz and glamour, that is for sure. And frankly, Pasadena doesn't even count as Los Angeles.
I think Hollywood is by far the most overrated tourist attraction in LA, and maybe even the United States. Just souvenir shops and tourists everywhere. They do have some cool bars and restaurants there though. I agree there are so many another awesome places to see in the area. The place I work at in TX is opening an office in Huntington Beach... I wouldn't mind moving...
But what "is" Los Angeles? It's such an enormous county and it's so diverse. You can be by a cool beach then drive 15 miles inland and you're in the hot desert. Santa Monica feels pretty removed from the city. Downtown feels different from Hollywood. Westwood, Pasadena, the Valley, Orange County all have a different feel to them. And that's what makes LA an awesome place I think.
