Welcome to GBTA - Michigan Chapter GBTA Michigan supports networking, education, and advocacy for corporate travel buyers and suppliers through in-person meetings, education days, and scholarship opportunities for members pursuing continuing education and certification programs. Our chapter is a community of industry professionals composed of travel buyers from recognized corporations from throughout the state — small and large — including the Automotive Big Three, the world's top office furniture manufacturers, a variety of OEM companies that support them, and many others. Equally important are the hoteliers, airlines, ground transportation agencies, travel management companies, and technology partners that bring about meaningful relationships resulting in strategic alliances.
