Narita or Haneda from LAX?
 

Advantages of one over the other? I know Haneda is closer to downtown Tokyo. Both flight choices on AA, same price, similar times.

It sort of depends where in Tokyo you are staying. Haneda is probably the better option, unless maybe if you are staying near Tokyo Station. But, in general, I find the relative convenience of Haneda to be kind of marginal frankly.
