Google, in seeking regulators’ approval for the ITA deal, said it would use ITA technology to “benefit passengers, airlines, and online travel agencies by making it easier for users to comparison shop for flights and airfares.’’ ITA, based in Cambridge, Mass., makes software that provides online flight and ticket information aggregated from the airlines.
