The Beat, a publication of The BTN Group, fielded an online survey in August 2017. In total, 204 qualified corporate travel managers and procurement professionals responded. To better represent managed travel programs, the findings exclude quantitative results from companies that in calendar year 2016 spent less than $500,000 on airfares from the U.S. point of sale, though qualitative input, such as open-ended questions, were considered from this segment. Respondents identifying themselves as consultants, travel agency representatives or other suppliers were also excluded from the results. Of the 188 corporate travel buyers whose responses were included, 24 percent spent between $500,000 and $2 million on airfares from the U.S. point of sale in 2016; 42 percent spent between $2 million and $12 million; 14 percent spent between $12.1 million and $20 million; 13 percent spent between $20.1 million and $50 million; and 7 percent spent more than $50 million in U.S.-booked air volume last year. Not all respondents answered all questions, and each chart in this study indicates the total number of respondents that did. The Beat supplemented these statistical findings with interviews with travel management company executives, corporate travel managers, procurement professionals, technology providers and consultants—some for attribution, others on background.
