Google’s $700 million acquisition of ITA Software, which powers many of the Web’s most popular travel search engines, has ruffled more than just a few feathers in the travel industry, The New York Times’ colleague Mickey Meece wrote on Monday.

Google, which announced its intent to purchase the company in July, has faced a wave of resistance from competitors, who are calling on regulators to block the deal on antitrust concerns. In October, several travel search sites, including Expedia, Travelocity and Kayak, formed a coalition called FairSearch.org to oppose the deal, arguing that Google could use ITA to “manipulate and dominate” the travel market, the group said in a recent statement.
