Charles de Gaulle Airport's Terminal 2 showing flight arrivals International airports have commercial relationships with and provide services to airlines and passengers from around the world. Many also serve as
hubs, or places where non-direct flights may land and passengers may switch planes, while others serve primarily direct
point-to-point flights. This affects airport design factors, including the number and placement of terminals as well as the flow of passengers and baggage between different areas of the airport. An airport specializing in point-to-point transit can have international and domestic terminals, each in their separate building equipped with separate
baggage handling facilities. In a hub airport, however, spaces and services are shared. Airport management have to take into account a wide range of factors, among which are the performance of airlines, the technical requirements of aircraft, airport-airline relationships, services for travelling customers, security and environmental impacts.
Standards Technical standards for safety and operating procedures at international airports are set by international agreements. The
International Air Transport Association (IATA), formed in 1945, is the association of the airline companies. The
International Civil Aviation Organization (ICAO) is a body of the
United Nations succeeding earlier international committees going back to 1903. These two organizations served to create regulations over airports which the airports themselves had no authority to debate. This eventually sparked an entire subject of air travel politics. In January 1948, 19 representatives from various US commercial airports met for the first time in New York City to seek resolution to common problems they each faced, which initiated the formation of the
Airport Operators Council, which later became
Airports Council International – North America (ACI-NA). This group included representatives from
Baltimore,
Boston,
Chicago,
Cleveland,
Dallas,
Denver,
Detroit,
Jacksonville,
Kansas City,
Los Angeles,
Memphis,
Miami,
Minneapolis-Saint Paul,
New York,
Philadelphia,
Pittsburgh,
St. Louis,
San Francisco and
Washington.
Flight logistics International airports have extensive operations in managing flight
logistics, such as
air traffic control. The latter service is provided by ground-based
controllers who coordinate and direct aircraft on the ground and through controlled airspace. Air traffic control also provides advisory services to aircraft in non-controlled airspace.
Customs and immigration Passport inspection at
Dublin Airport (2007) Airports with international flights have customs and
immigration facilities, which allow right of entry. These change over time but are generally designated by law. However, as some countries have agreements that allow connecting flights without customs and immigrations, such facilities do not define an international airport.
Security and safety , travelers to the United States can "
pre-clear" U.S. immigration (2008) The current trend of enhancing
security at the cost of passenger and baggage handling efficiency at international airports is expected to continue in the future. This places financial burden on airports, risks the flow of servicing processes, and has implications for the privacy of passengers. To ensure the viability of airport operations, new and innovative security systems are being developed. For instance, the old security checkpoints can be replaced by a "total security area" encompassing an entire airport, coupled with automatic surveillance of passengers from the moment they enter the airport until they embark on a plane. While these standards are regulated by
ICAO Standards And Recommended Practices (SARPs) and
WHO's
International Health Regulations (IHR), local authorities have considerable say in how they are implemented.
Transportation Among the most important airport services are further transportation connections, including rail networks, taxi and shuttle services at curbside pick-up areas, and public buses.
