Aviation is the transportation mode that connects nations, cities, businesses, and people to support a growing and vital global economy. Within the United States, aviation is essential to economic well-being. Aviation contributes more than $1.0 trillion annually to the U.S. economy and supports more than 10 million direct and indirect jobs, including more than one million manufacturing jobs. Aviation comprises more than five percent of the total U.S. gross domestic product. In the United States, more than $1.5 trillion in freight is transported by air every year and air travelers alone spend more than $635 billion a year. Globally, the aviation system is growing rapidly with the potential for more than five times as many passengers and 10 times the cargo in 2050 as today.
