Airports Council International
The Airports Council International (ACI) is an umbrella organization consisting of 641 members that deal with all aspects of airport management. Of these 641 members, a total of 1,953 airports are operated in 176 countries (as of January 2018). This also includes all major airports worldwide. In monthly and annual reports, the ACI publishes the traffic figures for passengers and freight traffic of its members with a 12-month delay. The official figures for 2022 will therefore only be available at the beginning of 2024 and will also be limited to the top 30 places.In total, there are 61 airports with a passenger volume of over 25 million per year, which the ACI classifies as major airports. Of these, around one third are located in North America and one quarter in Europe. The rest are spread across Asia, Australia and South America. None of the major airports are located in Africa.
IATA and ICAO codes

The aim of IATA is the international development of safe and economical air traffic. This includes, above all, the creation of standards such as ticket or booking systems. For example, it handles the booking and invoicing of over 400 million airline tickets every year.
The IATA codes are issued for airports (e.g., "SFO" for San Francisco), airlines (e.g., "LH" for Lufthansa) and aircraft types (e.g., "388" for an Airbus A380-800). The letters of an airport code usually have a connection with the name of the city. Only at very large airports does IATA assign a code that is not based on the city or region, but on the name of the airport, for example LHR (London Heathrow) or CDG (Charles de Gaulle).
A major drawback of the IATA codes is the limited selection of three-digit codes, which means that codes are assigned again after some time. Since IATA only issues an official list for a four-digit fee, several internet services are involved in collecting these codes. Unfortunately, this always leads to the listing of previously used codes for wrong airports and thus to apparent duplicates.
A further organization for international air traffic is the "International Civil Aviation Organization" (ICAO), which is a special organization of the United Nations (UN) and also assigns its own codes for airports, airlines and aircraft types. Unlike IATA codes, however, normal passengers rarely come into contact with ICAO codes. They are mostly used by pilots and air traffic control. They are recognizable by their four letters, which gives them an advantage over the IATA codes in that there are considerably more possible combinations and the same code is not assigned multiple times. Their more systematic structure also makes it possible to identify where an airport is located. The first two letters stand for the region and the country.
