This is the sixth in a series of reports that T2RL is publishing on the transformation that is finally under way in how airlines sell and deliver their services. There is a growing consensus that traditional processes based on technologies dating back to the middle of the 20th century need a significant update. In these reports we describe the new structures and, more importantly, describe the path that the industry will have to take in order to implement them. This instalment considers the changes that will be necessary in delivery systems if the full promise of new commercial processes is to be realised at the point where the customer accesses the services sold.
