What is IATA and how does it work?

The Chicago Convention of 1944 established the first civil aviation agreement, setting the foundation for regulating air travel. This led to the formation of the International Civil Aviation Organization (ICAO) to oversee global aviation standards and agreements.

With increasing air traffic and chaotic pricing post-WWII, the International Air Transport Association (IATA) was created in 1945. IATA's initial role was to assist ICAO in addressing commercial aviation problems, such as standardizing rates, fares, revenue allocation, and ticketing processes.

Today, IATA comprises 290 airlines from 120 countries, representing 82% of scheduled air traffic. It plays a crucial role in designing and implementing universally accepted standards, even for non-member airlines, through the use of IATA codes for reservations, accounting, baggage handling, and location identification.

IATA represents airline interests, lobbies for operational improvements, and supports initiatives like NDC (New Distribution Capability) to enhance service distribution. It also regulates travel agencies through accreditation, ensuring smooth transactions and protecting airlines, and processes sales reports via its billing and settlement software.

While IATA's initiatives are largely beneficial, some, like the 2015 'cabin okay' baggage size proposal, faced backlash due to significant size reductions. IATA's annual priorities include growing NDC adoption, implementing RFID technologies, attracting low-cost carriers, cutting airport costs, and building wider air travel infrastructure.
