Hi,
I may not be entirely correct on this one but to the best of my knowledge it can, although with a payload restiriction, so they don't use the -300's to LAX. One of the new aircraft is a -302 and I believe it can operate the route as it has extra fuel tanks (I may be mistaken). Remember that one of the new A330's is a -200 series so I guess that aircraft operates the route as well as the existing -200s. Personally i'm not a fan of EI l/h so would rather give it a miss.
