Civil aviation transport flights operate according to prescribed routes, including direction, starting and ending points, stopover points, route width, and flight altitude. The general trend of international routes is east-west, concentrated in the mid-latitudes of the northern hemisphere, roughly forming a circular aviation belt. The countries and regions with the densest international routes are Europe, North America and East Asia, and the busiest seas are the North Atlantic and North Pacific. On the basis of the latitudinal aviation belt, a certain longitudinal route distribution is formed by radiating from the route-dense areas to the south. The world’s busiest air routes and aviation hubs are as follows.
(1) The North Atlantic route between Western Europe and North America is one of the oldest and busiest international routes in the world. This route covers the area between Europe and the east coast of North America. The route mainly connects aviation hubs such as Paris, London, Frankfurt, New York, Chicago, and Montreal.
(2) The North Pacific route between North America and Asia is located over the Pacific Ocean between North America and Asia, from the west coast of North America to the east of Asia, and is the world’s longest transoceanic route. This is an air route from airports such as Beijing, Hong Kong, and Tokyo to airports such as Vancouver, Seattle, San Francisco, and Los Angeles on the west coast of North America via the North Pacific Ocean, and can be extended to airports on the east coast of North America. Honolulu in the central Pacific is the main relay refueling station for this route.
(3) South Atlantic route, between the South Atlantic region (South America) and Southeast Asia, passing through the Atlantic Ocean and Central Africa, South Africa, and Indian Ocean islands or direct flights. Such as Mauritius, South Africa, and Sao Paulo routes.
(4) Western Europe-Middle East-Far East air route. This route connects major airports in Western Europe to airports such as Hong Kong, Beijing, and Tokyo, and passes through important airports such as Athens, Cairo, Tehran, Karachi, New Delhi, Bangkok, and Singapore.
In addition, Latin American routes, polar routes, Australia and New Zealand routes, etc. are also relatively major routes.
Airport:
An airport is a stopover point for air transportation, also known as an airport or airport. It is a place for aircraft to take off, land, park, and organize and ensure aircraft activities. There are currently about 49,000 airports in the world, mainly distributed in America and Europe.
