The global airline industry was worth $686 billion in 2020, representing an 18% drop from the $828 billion it generated the previous year.

Much of this decrease in revenue was due to lower travel demand caused by the coronavirus pandemic and related travel restrictions.

Although it’s yet to be seen whether the industry will recover in 2021, many reputable experts are optimistic and project growth figures as high as $776.86 billion.
