Matt,
I second patricks on the EVA Air recommendation. She would transit through Taipei, Taiwan on EVA. If comfort and in-seat TV unit is important, be sure to choose the Evergreen Deluxe class of service, because their standard economy section doesn't have personal TV units in the back of the seats. EVA Air is a partner of American Airlines.
My fiancee called Cathay Pacific (I've flown them everytime to VN; love the comfort and HKG) in Sai Gon and they quoted her a one-way fare from SGN to STL - transit in Hong Kong and Los Angeles - for $715 (including taxes). We don't have a choice in airline for her because I'm already ticketed on Cathay Pacific for my return after my contract is complete here in Vietnam.
Let her call around to some airlines in Sai Gon (i.e. Korean Air, Asiana Air, Japan Airlines, Singapore Airlines, etc.) for some fares. However, a transit in Hong Kong, Singapore or Taiwan is nice because of their close proximity to HCMC. Better than a 6 hour flight to Japan or Korea and then another long one into the United States.
Hope that helps!

So cheaptickets.com, priceline, travelocity, etc only allow you to do comparisons for flights starting in the USA. The only way I am seeing right now to check for rates from Vietnam to the USA is to go to each airline's website and many don't even have a Vietnam option!
I checked China Airlines and I think I found flights from Hong Kong to NYC for under $600 US dollars (I imagine taxes will knock that up to near $700). What have people done in the past? I used my frequent flyer miles to go Business on my way home from Saigon last month, so I cannot get a free ticket for her.
