The aviation association IATA is looking ahead to summer 2021 with great concern.

IATA has now drawn up various scenarios and the worst case scenario is that volumes in 2021 could be only 38 percent of those in 2019. If this were to happen, the survival of many providers would be at stake. IATA President Alexandre de Juniac said it would "make a tough year even tougher." The approval of the Biontech-Pfizer vaccine sparked new optimism in the aviation and tourism industries.
