Mirroring its impact on aviation, the COVID-19 pandemic has had a significant impact on airline companies due to travel restrictions and a slump in demand among travelers. Several airlines have declared bankruptcy, with some ceasing operations, while other airlines reported historic reductions in flights, as well as accelerating retirements of certain aircraft types, such as the Airbus A340, Airbus A380, or the Boeing 747. By 8 October 2020, 43 commercial airlines had gone bankrupt, and many more were expected to follow.[1] In late October 2020, ACI Europe stated that 193 (mostly regional) of the 740 airports in Europe were also risking bankruptcy.[2]
