I heard a comment on this site, kayak.com, last night on the travel channel. Man, it is cool. They link directly to the hotel/airline/car agency to purchase the item at the listed price and when you click through they have you setup and ready to purchase.
If this site is not owned or operated by Google I would be surprised. Just take a look at it and tell me it doesn't look like "Google Travel". The functionality is great and a good user experience.
