I dig it, cool domain. I hear .la is doing pretty well as far as international TLDs go. If you find the right buyer it could be worth $x,xxx, but finding that buyer may be tough. I'd hang onto it, put some content up, and see if you get any bites. Even though the airlines aren't doing too well, cheap flights are and the domain definitely has obvious commercial value. I think if you can sell it to someone for 100, you can get a 1000 - its just whether it hits someone in the right way.
It sounds ok, but it's a very limited market to just fly to LA. I think this name needs to be developed to have much value, otherwise, Mid $xx
