This document summarizes aviation's economic impact and growth projections. It notes that aviation currently supports 58 million jobs and $2.4 trillion in global GDP, comprising 3.4% of the world's GDP. Aviation is projected to support 105 million jobs and $6.4 trillion in global GDP by 2035, as passenger numbers grow by 3.6% annually to over 3.1 billion new passengers. Failure to expand global airport capacity sufficiently could result in 2 million lost jobs, 225 million lost passengers, and $110 billion in lost revenues by 2035.
