The German tour operator market has undergone a profound transformation in recent years. While the individual components of the entire tourism value chain operated largely independently until the 1990s, today large tourism corporations serve the entire travel market, from booking to individual charter flights. The main objective of this book is to systematically present the existing German and European tour operator market. In addition to the current analysis of the situation in German and global tourism, the study focuses on the market mechanisms within the German tour operator market. The central emphasis of this investigation includes a detailed structural and concentration analysis of the German tour operator market. The results of this study describe the consequences.
