This updated edition of The Economics of Airlines offers a solid and well-structured introduction to the key economic forces shaping the airline industry. The author effectively explains complex concepts, drawing on both theoretical foundations and industry practices. The inclusion of recent developments, such as the impact of Covid-19, the growing importance of cargo, changes in cost structures, and environmental constraints, makes the book particularly relevant today. The chapters on pricing, competition, and regulatory frameworks are especially strong, with clear explanations and up-to-date examples. We use this book for our Advanced Master’s students in Air Transport Management. However, it could also be easily used by students in transport management, as well as professionals seeking a concise yet comprehensive overview of how airlines operate within a challenging economic environment.
