An international flight is a form of commercial flight within civil aviation where the departure and the arrival take place in different countries.[1]
An important difference between international and domestic flights is that, before boarding the aircraft, passengers must undergo migration formalities and, when arriving to the destination airport, they must undergo both immigration and customs formalities.
Airports serving international flights are known as international airports.
One of the first flights between two countries was on January 7, 1785, when Jean-Pierre Blanchard and John Jeffries crossed the English Channel in a balloon.[2] It took more than a century for the first heavier-than-air object to repeat this prowess: Louis Blériot crossed the Channel on July 25, 1909,[3] winning a Daily Mail prize of £1,000.[4]
Aviation technology developed during World War I and soon came the development of international commercial flights in what is known as the Golden Age of Aviation; there was a combination of aircraft types which included airships and airplanes. The first airline was Chalk's Ocean Airways, established 1917, which operated scheduled seaplane services from Florida to the Bahamas. The first the first regular international service in the world was covered by the British Aircraft Transport and Travel, from Hounslow Heath Aerodrome to Le Bourget.
After World War II, international commercial flights were regulated by the creation of the International Air Transport Association and the International Civil Aviation Organization.
Nowadays, several international flights are also non-stop flights.

International mostly means something (a company, language or organization) that involves more than one country. The term international as a word means involvement of, interaction between or encompassing more than one nation, or generally beyond national boundaries. For example, international law, which is applied by more than one country over the world, and international language which is a language spoken by residents of more than one country.
In American English, "International" is also commonly used as a euphemism for "foreign" or even "foreigner."
The term international was coined by the utilitarian philosopher Jeremy Bentham in his Introduction to Principles of Morals and Legislation, which was printed for publication in 1780 and published in 1789. Bentham wrote: "The word international, it must be acknowledged, is a new one; though, it is hoped, sufficiently analogous and intelligible. It is calculated to express, in a more significant way, the branch of law which goes commonly under the name of the law of nations. The word was adopted in French in 1801.Thomas Erskine Holland noted in his article on Bentham in the 11th edition of the Encyclopedia Britannica that "Many of Bentham's phrases, such as 'international,' 'utilitarian,' 'codification,' are valuable additions to our language; but the majority of them, especially those of Greek derivation, have taken no root in it."
Flight is the process by which an object moves, through an atmosphere (especially the air) or beyond it (as in the case of spaceflight), by generating aerodynamic lift, propulsive thrust, aerostatically using buoyancy, or by ballistic movement, without direct support from any surface.
The engineering aspects of flight are studied in aerospace engineering which is subdivided into aeronautics, which is the study of vehicles that travel through the air, and astronautics, the study of vehicles that travel through space, and in ballistics, the study of the flight of projectiles.
Humans have managed to construct lighter than air vehicles that raise off the ground and fly, due to their buoyancy in air and water.
An aerostat is a system that remains aloft primarily through the use of buoyancy to give an aircraft that has the same overall density as air. Aerostats include free balloons, airships, and moored balloons. An aerostat's main structural component is its envelope, a lightweight skin containing a lifting gas to provide buoyancy, to which other components are attached.
