This is the third edition of T2RL’s report on retailing in the airline industry. The first edition was prepared and distributed in August 2011. It was updated again in 2016. This edition, published in May 2017, follows on from the six airline retailing opportunities detailed in the last report (Upsell, Cross-sell, Loyalty & Redemption, Digital Marketing & Conversion Optimisation, Revenue Management Optimisation and Multiple Distribution Channels) and expands this model to include three more in the areas of Mobile, Air Pricing and Servicing. The data is derived from T2RL’s extensive research and experience of working with airlines and vendors on the application of information technology to real airline distribution and retailing challenges.
