Abstract
Aviation, like other transport modes, is essential for the economy; it facilitates business and trade, allows people to connect with different regions/cities, and generate tourism. Air traffic at the country or regional level is quite interesting by analyzing and comparing its relative contribution to the worldwide air transport volume of passengers, considering domestic and international transport. As a result, the impact and importance of aviation for passengers vary by geography, giving a better understanding of how regions concentrate passengers’ air traffic volume. It also provides a global overview of the development and concentration of future growth.
