Google has started rolling out a tool that lists airline rates within their search results. The results link directly to their airlines’ websites rather than online travel agency websites like Kayak, Expedia, Orbitz, Travelocity, Priceline, etc.

Google Inc. (NASDAQ:GOOG) has acquired 57 companies through September according to an SEC filing from the company. Not bad considering that Google acquired 48 companies in 2010. In three deals alone, Google spent $941 million reports the 10-Q statement. The $941 million was spent on $$676 million for ITA Software, $151 million for Zagat, and $114 million for Daily Deals. Google also bid $12.5 billion for Motorola Mobility, but that deal is not expected to close until 2012 due to regulatory reasons. [eWeek]

Google Inc. (NASDAQ:GOOG) has started adding flight search information to their search results. This feature does not utilize technology provided by ITA Software, a company that Google acquired for $700 million. When you looking for a destination on Google, you can see which airlines go on that route. For example, if you search for “New York to Chicago,” you will see the schedules of all the non-stop flights that are on that route and the timings. Google software engineer Petter Wendum said that the company is eager to develop software that is integrated with ITA software, but the Department of Justice has conditions. [TechCrunch]

The Department of Justice has cleared Google’s $700 million acquisition of ITA Software. However Google must comply to a proposed settlement. Google will have to develop and license travel software, fund software research in the industry, and establish internal firewall procedures. Google will also have to license ITA’s airfare search software on commercially reasonable terms.

Kayak.com has filed an S-1 statement with the SEC for a proposed IPO. Kayak hopes to raised $50 million according to the S-1. During the first 9 months of 2010, Kayak made about $128 million in revenues. This is a 48% jump from the year before. During the third quarter ending September 30, Kayak made about $48 million in revenues. Between January and September, Kayak.com processed over 469 million user queries.

As you may remember, Google Inc. (NASDAQ:GOOG) has acquired ITA Software in July 2010 for $700 million. ITA Software is the provider of flight data for many travel websites including Kayak.com, Farelogix, Sabre Holdings, and Expedia. These companies are also forming a coalition called FairSearch.org in order to persuade the Justice Department to block the deal.
