Online Travel Booking and Bidding Agencies - Travelocity handling of multiple city routing

I'm trying RDU-BKK-SFO for dep 12/15/03 and returning 1/11/04. Travelocity doesn't seem to handle multiple cities well. It returns a fare of $5000+; Orbitz finds a $1300+ fare.

There must be a flaw in the Travelocity search engine for multiple cities. Anyone know how to get Travelocity to do this right?

No, but try itn.net also, as they do it still another way.
