Introduction and Overview

The objective of Volume 11, Advance in Airline Economics, is to provide new insights on the multidimensional impacts of the COVID-19 pandemic on the aviation sector in general and airlines in particular. The billions of airline passengers combined with conditions associated with airline travel and airports create a conducive environment for the rapid spread of viruses. The COVID-19 pandemic impacted airlines, airports, and their operations significantly. Presently, the virus's threat to global public health, although a continuing concern, is significantly diminished.¹ As nations' economies are returning to prepandemic environments, this volume is timely for assessing the pandemic's diverse impacts on the aviation sector, how airlines reacted to the pandemic, worked with governments, and adapted its operations and business models.
