Larry Page: It would be really nice to have a system that could basically vacation plan for you. It would know your preferences, it would know the weather, it would know the prices of airline tickets, the hotel prices, understand logistics, combine all those things into one experience. And that's kind of how we think about search.
At high level - very possible. [ A to B flights, hotels without detailed customer preferencing , auto hire ].
At detailed level - very impossible on current data. If Google has a crack at this it will push the travel market more heavily towards alternatives that service the customer better. Simply, you can rarely find what you want online - much better, considerably better data is required and that's only part of it.
e.g. I just got back from a trip to the Middle East. I wanted a room at a specific hotel with a view of a particular icon on a specific floor, with late check out, and other specific servicing needs. Nothing online could do it. The whole thing had to be negotiated.
The US/Canada market is far more focused on supermarket / commodity style travel than the rest of the World, where variants are a much larger slice of the market. So either Google does search, or it does "knowledge engine" - and it has to be far better than any current online service or it will loose reputation fast.
