As is the custom when Google makes a new acquisition, U.S. antitrust regulators are eyeing the search giant's planned purchase of ITA software. If you'll recall, when Google first announced its intent to buy the travel data provider, the Federal Trade Commission and the Department of Justice were in talks to determine which agency would handle the antitrust review.
It seems the DOJ has the privilege this time, and the agency needs more information from both parties before it can make decisions. According to an IDG story in BusinessWeek:
Google received the formal "second request" for information from the DOJ last week regarding the company's agreement to buy ITA, a maker of air-travel flight-information software, for $700 million in cash.
Google is interested in the ITA software as a means of improving users' travel-related search experiences, but some observers have said the DOJ may reject the deal simply because the software is a "key component" of online travel services.
