One in four travel buyers say over 40 percent of their traveling workforce is now made up of millennials, according to a new report  from GBTA in partnership with Cvent, the meetings technology company. According to the report, called “The Travel Buyer of the Future: What’s on the Horizon for the Ever-Changing Landscape of Travel and Meetings Management,” over half of buyers say millennials tend to push the boundaries of corporate travel policy, and three-quarters say millennials demand different, more consumer-like tools out of their company’s travel program. Despite this, according to the research, only one in five travel buyers say they have changed their travel policy in response to an increasingly millennial workforce. Aside from the impact of millennials, the research also showed that globalization and disruption in suppliers will be major trends in coming years. Scott Solombrino, GBTA’s executive director, said the research suggests buyers “may be relying too much on technology to be the change agent versus making strategic choices to act, rather than react, in the face of change.”
