Via Digg, Google is likely to build a travel site (may be slow from Digg effect). Reuters also reports on this. Google already supports from travel features in it’s main index. For example, type in "london jfk" and it’ll allow you to find flights from London to the JFK in New York. Boppers typing in "london paris maybe tokyo" will be offered flights from London to Paris.
It does kind of make sense looking at Google’s current features. Using Google Maps you can find directions to your hotel, using Google Calculator you can convert currency, using Google Answer you can find information on your destination, you can already find flights and Google has a shopping portal, Froogle.
Although to argue this fits into Google’s original vision of search would be tough 🙂 Jeremy Zawodny says Google is building Yahoo 2.0 🙂
