ITA Software
ITA Software, Inc. was an American software company specializing in advanced algorithms and systems for air travel search, optimization, and pricing. Founded in 1996 by Jeremy Wertheimer, a computer scientist from the MIT Artificial Intelligence Laboratory, along with associates in Cambridge, Massachusetts, the company developed proprietary technology to handle complex flight itinerary queries and fare data processing.[1][2] ITA Software's core innovation was its QPX engine, a sophisticated software platform that enabled rapid analysis of vast airline schedules and pricing matrices, powering tools for airlines, travel agencies, and online search services.[2] This technology addressed longstanding inefficiencies in travel booking by applying constraint-based optimization and heuristic search methods to generate optimal itineraries, becoming a standard in the industry for its speed and accuracy in handling combinatorial complexity.[1] The company's systems were licensed to major players, facilitating more dynamic and comprehensive fare comparisons than traditional global distribution systems. In July 2010, Google announced its acquisition of ITA Software for $700 million in cash, a move aimed at enhancing its travel search capabilities amid competition from sites like Kayak and Expedia.[3] The deal faced scrutiny from the U.S. Department of Justice over antitrust concerns, requiring Google to commit to developing and licensing rival travel software before approval in April 2011.[4] Post-acquisition, ITA's technology integrated into Google Flights, enabling advanced features like flexible date searches and price predictions, while the original ITA team continued operations under Google (now Alphabet Inc.).[5] This acquisition marked a significant expansion of Google's role in vertical search markets, leveraging ITA's expertise to challenge established online travel intermediaries.[3]
