TripIt, the online travel assistant that debuted at Techcrunch40 and is one of the sites Michael can’t live without, has received $5.1M in Series B funding.

The main contributions for this round come from Sabre Holdings, O’Reilly AlphaTech Ventures, and European Founders Fund. This addition brings the site’s total funding to $6.1M.

TripIt’s main goal is to simplify travel. Users need only forward email confirmations from airlines, hotels, and other travel services, and TripIt generates a simplified comprehensive list of travel plans. TripIt recently launched a mobile version of the site, and also features Closeness Matches, which notify users when they are in the same region as a friend.

O’Reilly AlphaTech Ventures, which contributed to this round, was also responsible for TripIt’s $1M Series A funding round.
