zrs70, you are a real mensch for digging around for a 'replacement' for UCNXN. I did regisiter with this site in the past, so I dug out my username and password, and gave it a spin with my normal ex-BKK itineraries. I remember that in the past, it was strange that had to ally myself with a travel agent to use this engine. In any event, the speed with which the flights were returned was very good. The overall display is quite clean. The only drawback was that the flights priced out anywhere from 2x (BKK-LAX) to 5x (BKK-JFK) the normal prices in economy, although the business prices were only about 20% higher (it seemed as if the prices were based on ex-USA instead of ex-BKK, and were simply being calculated in Thai Baht).
As I noted near the top of this topic, perhaps the Galileo web version is more suited for people who fly domestically in the US.
Again, thanks for the link. I was worth another look.
