here in CA, pretty much only china airlines and united...if you can afford it, go with united, better service for sure (i've flown china airlines 3 or 4 times roundtrip, no problems whatsoever, united only once)
be sure to book a return flight and get it confirmed if you go with china airlines, i was stuck in a dandy and had to pay various 'fees' to get back to the US in time for school
