IATA standardises airport terminal design and equipment
The International Air Transport Association (IATA) is the trade association for the world's airlines, representing over 340 airlines and covering more than 80% of global air traffic. IATA was formed to provide international air carriers with a mechanism to fix prices and set fares.
IATA plays a role in standardising airport terminal design and equipment. They offer training courses on airport terminal planning and design, covering topics such as optimal passenger flows, capacity, and infrastructure design. The courses are facilitated by experienced and accredited subject matter experts who set industry standards.
IATA's training on terminal design equips professionals with the skills to create customer-centred airport layouts and navigate complex aerodrome operations. The courses provide a comprehensive overview of airport terminal planning and design, helping professionals build upon their existing experience and expand their knowledge.
IATA's standardisation of airport terminal design and equipment ensures that terminals can flexibly respond to future challenges and opportunities. This includes considering changes in business and regulatory environments, such as shifts in airline business models, traffic patterns, security requirements, and customs and immigration needs.
By standardising terminal design and equipment, IATA helps airports provide efficient and effective services for both passengers and airline companies. This standardisation also contributes to the overall safety, productivity, and high-speed operations at airports.

IATA codes are assigned to airports
An IATA airport code, also known as an IATA location identifier, is a three-letter geocode designating many airports and metropolitan areas globally. IATA stands for the International Air Transport Association, which is the trade association for the world's airlines, representing around 340 airlines and over 80% of global air traffic.
The IATA code is determined by first ensuring that it is unique and not in use by any other entity. The code is typically assigned based on the name of the airport, the name of the city, or some other meaningful and relevant identifier if those letters are already taken. For example, Chicago's O'Hare airport is assigned ORD based on its old name of Orchard Field, and Athens International Airport is ATH. Some codes are harder to decipher, such as Louis Armstrong New Orleans International Airport's code, MSY, which is named after the aviator John Moisant.
IATA codes are essential for the identification of an airline and its destinations and are integral to the smooth running of hundreds of electronic applications built for passenger and cargo traffic. They are also used for baggage tags attached at airport check-in desks. The assignment of these codes is governed by IATA Resolution 763 and administered by the IATA's headquarters in Montreal, Canada.
The IATA stepped in during the 1960s when the airlines decided they needed a standardized process to avoid confusion. The IATA also provides consulting and training services and defines standards for terminal designs and equipment standardization.

IATA's history of price fixing
IATA is an acronym for the International Air Transport Association, which is the trade association for the world's airlines, representing some 340 airlines and over 80% of global air traffic. IATA was formed following the Chicago Convention, which did not result in a consensus on the economic regulation of the airline industry. Warren Koffler stated that IATA was formed to fill the void left by the Chicago Convention and to provide international air carriers with a mechanism to fix prices.
In the late 1940s, IATA started holding conferences to fix prices for international air travel. In 1947, IATA operated as a cartel, charged by governments with setting a constrained fare structure that avoided price competition. The first Traffic Conference was held in Rio de Janeiro in 1947, where unanimous agreement was reached on some 400 resolutions, with about 200 related to establishing a uniform structure for tariffs charged for international air transportation.
In the early 1950s, IATA's price-fixing regime forced airlines to differentiate themselves through the quality of their passenger experience. In response, IATA imposed strict limits on the quality of airline service, including a formal ruling in 1958 barring airlines from serving economy passengers sandwiches with "luxurious" ingredients. The American Civil Aeronautics Board did not intervene to stop IATA's price-fixing, leading law professor Louis B. Schwartz to condemn the board's inaction as an "abdication of judicial responsibility".
By the late 1970s, IATA's price-fixing regime was seen as unattractive by many major airlines, who chose to forgo IATA membership. During its time as a cartel, IATA set and enforced the fares that its carriers charged, with the backing of most relevant governments. In 1977, IATA members allegedly conspired to undercut prices on shared routes to bankrupt Laker Airways, which sought to disrupt IATA's price-fixing regime.
In 1973, 94% of international scheduled passenger traffic flew on IATA carriers. However, charter carriers, which accounted for up to 28% of international traffic in 1972, posed competition to the IATA cartel system. "Special fares", or discounts from standard fares, were introduced by IATA in response to this competition. Despite this, by the late 1970s, many airlines saw IATA's price-fixing regime as unattractive, and some chose to forgo membership.
