Two major recessions have plagued the world this millennium. The Great Recession of 2008 was, at the time, the worst recession since the Great Depression of the 1930s.

Unfortunately, the pandemic-caused recession of 2020 was deeper and more damaging to the retail and services sectors including the airline industry. Use the theory of supply and demand to predict the effect of the 2020 recession on airline demand (the willingness and ability of people to purchase airline tickets), supply (the willingness and ability of airlines to provide flights), and price (the average price of an airline ticket).
