Air transport also provides entrance to international markets and assists in the progress of world trade. Some 61.5 million metric tons of cargo was carried by air in 2017, generating around 95.9 billion U.S. dollars in revenue.
Contrary to road or rail transportation, the aviation industry has to pay for most of its own infrastructure and maintenance such as runways, terminals or air traffic control. In 2016, airports spent close to 69 billion U.S. dollars in infrastructure with Asia Pacific accounting for the majority of new airport projects in the region.
The aviation industry provides a total of 62.7 million jobs worldwide. It directly generates employment opportunities within the airlines, air navigation services providers and airport operators and additionally creates jobs via the supply chain in the transportation of goods and services.
