A lot of ground was covered during Peter Kern’s appearance at Skift Global Forum in New York City on September 21. The vice chairman and CEO of Expedia Group gave his take on technology, micro-services, mergers and acquisitions, and outlined why the online travel agencies still only control around 20 percent of a “multi-trillion dollar” travel market. "There’s huge opportunity," Kern says. "You just have to innovate the products and innovate the business model over time." And of course he (delicately) responded to comments made earlier at the forum by Barry Diller, the chairman and senior executive of both Expedia Group and IAC, that working from home was “kind of stupid” and “a crock,”while in discussion with Skift founder and CEO Rafat Ali.
