More than 70 percent of employees hold Federal Aviation Administration certification and licenses. CAVOK has actively sought people with in-depth understanding of all facets of airline operations, and the results for the client are significant, measurable, and sustainable.

Founded in 1996, CAVOK was acquired by Oliver Wyman in 2007 and draws on the consulting firmís strategic and operational expertise in aviation. By combining CAVOKís operational knowledge with Oliver Wymanís management consulting experience in the aviation industry, our clients gain access to unique depth and breadth of experience, tools, and acumen.
