For more than thirty years, air transport has made great progress in terms of security and safety. Every year new systems and innovations save about $2 billion, and yet every year the industry loses about $5 billion in a market that grows at an average of 5 percent per year. Something is clearly wrong. Jean-Louis Baroux has been working in the airline industry for more than forty years. In this book, he presents a global vision for air transport and examines why only low-cost airlines are profitable. As for the rest, Baroux argues that they have lost touch with their clients and passengers, which is one of the main reasons why they have become unprofitable. He analyses the way air transport is managed and provides much-needed ideas and suggestions to make the industry profitable again.
