Congrats to former Hotwire (Expedia-purchased) colleague Gregg Brockway on the launch of TripIt.com (http://www.tripit.com) at the TechCrunch40 event happening this week in California.

TripIt is a kind of pull-it-together travel itinerary tool, whereby you can make reservations in multiple locations and still end up with a single itinerary. In Gregg's words:

"TripIt helps you organize your travel plans. You simply forward all your travel confirmation emails to TripIt and we automatically create a master itinerary with your combined plans plus daily weather, local maps, directions and more. Then you can expand your master itinerary and share it with your friends"

It's not hard to see other possible revenue sources via affiliate relationships, meta search or advertising. As more of the US market's vanilla air / hotel / car business continues to move from third parties to suppliers, this type of a service starts to make a lot of sense.
