On a recent Thursday, Hipmunk's CEO, Adam Goldstein, laid out his travel plans. He'd just returned from London, but the following week would take him to New York, Los Angeles, home to San Francisco, then to Seattle, San Jose, and back to New York. "It's slightly more traveling than usual, but not that crazy," Goldstein says. On deck were meetings with airline and search-site executives, and plans to build strategic partnerships within the travel industry.
