A large majority (72%)  of corporate travel buyers say their programs are only somewhat integrated, according to a survey from the Association of Corporate Travel Executives (ACTE), in collaboration with American Express Global Business Travel (GBT). The study, called “The Journey to Integrated Travel Management,” examines how evolving technology and the varying needs of organizations’ stakeholders create barriers and gateways to true program integration. Online booking tools are the most commonly integrated element of respondents’ programs (92%), followed by corporate cards (74%) and expense management platforms (60%). In terms of drivers of integration, travel managers rank visibility and control of expenses (70%), improved user experience (65%) and duty of care {58%) as their top three priorities. Almost a quarter (22%) of travel managers have no further plans to integrate. Respondents identify a number of barriers to progress, including lack of resources (25%) and a perceived lack of internal and stakeholder support (30%). However, business travelers pose the biggest challenge to integration, with 37% of respondents reporting traveler adoption and unwillingness to change as their top barrier – despite the fact that travelers are also one of the main drivers for end-to-end integration, cited by more than a third (34%) of respondents.
