LAX Airport Careers?

Ok, I'm near the end of my junior year in high school. So I'm starting to think about a career. Something that interests me is, working at LAX International Airport. Can someone give me, some job descriscptions, that involve working at any airpot. And maybe throw in some advantages and also, disadantages. Thank you!

A relative of mine is a LAX Police Officer. He works a lot of weird hours, but his pay is pretty decent.
