This is the fourth edition of T2RL's analysis on the market recovery for the airline industry during and after the COVID-19 pandemic. The world is a very different place today than it was this time last year, and even more dramatically different from 2019. It is also now apparent that some of the changes seen in the past year are here to stay for quite some time. This report examines the impact of the vaccine rollout on international travel and effects the current climate is having on airline IT contracting, distribution and technology.
