What Is IATA: Definition, Meaning, Examples

International Air Transport Association (IATA)

The International Air Transport Association (IATA) is the global trade association for the world’s airlines, representing about 300 airlines that account for 83% of total air traffic. Far more than a lobbying group, IATA is the operational engine of the aviation industry, with responsibility for formulating industry policy, setting technical standards (such as baggage rules and ticketing formats) and managing the massive financial settlement systems that permit money to flow from one travel agency to another airline.

Language of Aviation: Codes and Standards

To the travel technology sector, standardization is IATA’s most visible contribution. Without IATA the global reservation network would not have a common language.

  • Location Identifiers: IATA allocates the 3-letter airport codes (e.g., LHR, Heathrow, JFK, New York) and 2-letter airline designators (e.g., BA, British Airways, LH, Lufthansa). These codes are the primary keys of all the GDS and booking engine databases.
  • Data Standards: IATA is the driving force behind the development of communication protocols. They are the architects behind EDIFACT (the legacy standard) and NDC (the modern retailing standard) which ensure that a reservation system in Japan can technically communicate with an airline server in Germany.

Financial Clearinghouse: BSP and CASS

IATA’s most important operational function is that of the industry’s central bank under the Billing and Settlement Plan (BSP).

In a world without BSP, to sell tickets to various airlines, a travel agency would have to write separate checks to each airline they sold a ticket for (one for United, one for Emirates, one for Qantas). Instead, the BSP acts as a consolidator:

  • Aggregation: The travel agent sells tickets for 50 different airlines all through the week.
  • Single Payment: At the end of the remittance period, one single payment is sent to IATA by the agent.
  • Distribution: IATA divides the money and distributes it to the related airlines. Note: This system is called ARC (Airlines Reporting Corporation) in the USA, but is functionally the same as IATA’s BSP.

IATA vs. ICAO: The Critical Difference

People tend to confuse IATA and ICAO, but both of their mandates are absolutely different.

  • IATA (International Air Transport Association): A Private Trade Association. Its members are airlines. It is focused on commercial viability, ticketing, and customer service standards.
  • ICAO (International Civil Aviation Organization): UN, Specialized Agency. Its members are governments (states). For example, it focuses on borders, passports, international law, and safety treaties.

Frequently Asked Questions

What is an IATA number?

It is a special 7-digit numeric code assigned to IATA-accredited travel agencies. This is used as a badge of verification so that the agency issues airline tickets and receives commissions. Without it, an agency normally can’t sell flights directly.

What is ONE Order?

ONE Order is an IATA project to modernize airline accounting. It aims to replace the many hard coded records that are now used (PNR, E-Ticket, EMD) with one flexible retail order record, comparable to an Amazon shopping cart receipt.

Does IATA set ticket prices?

No. IATA used to hold price-setting conferences decades ago but this practice was banned on account of anti-trust laws. Today, the airlines decide their own prices depending on market competition.
