I have been studying the business travel market for the past year and have been surprised by how little concrete information there is on business travel as a market segment. Leisure travel can be segmented into many known categories - independent travelers, adventure travelers, voluntourists, etc. But so much less is known about sub-segments of business travel. I thought this book was very helpful at creating a theoretical framework for analyzing the business travel market and had some useful case studies for those who want to work in business travel, especially events planning and travel management. I liked the book and found it useful, although I wish that the authors had been able to provide deeper analysis of the diverse business travel market segments.
