IATA & ICAO — Role, Membership, Functions & Importance in Global Aviation
Two organisations shape every aspect of global aviation — IATA and ICAO. One is a trade body for airlines. The other is a UN agency for governments. Together, they set the standards, rules, codes, and policies that make 100,000 daily flights possible.

IATA is the trade association of the world’s airlines. Mission: “to be the force for value creation and innovation driving a safe, secure and profitable air transport industry that sustainably connects and enriches our world.”

🎯 IATA’s 3 Core Missions
Representing
Improving understanding of the air transport industry among decision-makers. Increasing awareness of aviation’s benefits to national and global economies.
Leading
Developing global commercial standards upon which the air transport industry is built. Setting the rules of the game for all airlines.
Serving
Helping airlines operate safely, securely, efficiently, and economically under clearly defined rules.
⚙️ IATA’s Key Functions & Services
A. IATA Accreditation
IATA accredits travel agents — authorising them to sell domestic and international airline tickets on behalf of IATA member airlines. Accredited agents access BSP (Billing and Settlement Plan) — the efficient invoicing and payment interface between agents, airlines, and transport providers. Also accredits cargo agents globally.
B. IATA Codes
IATA assigns unique codes to airlines, airports, cities, and countries:
Airlines: 2-letter alphanumeric code (e.g., Air India = AI, IndiGo = 6E, Jet Airways = 9W)
Airports/Cities: 3-letter alpha code (e.g., Delhi = DEL, Mumbai = BOM, London = LHR)
Countries: 2-letter alpha code (e.g., India = IN, USA = US, UK = GB)
Flights: Airline code + flight number (e.g., 9W442 = Jet Airways Bangalore-Singapore at 2035 hrs)
Airlines: 2-letter alphanumeric code (e.g., Air India = AI, IndiGo = 6E, Jet Airways = 9W)
Airports/Cities: 3-letter alpha code (e.g., Delhi = DEL, Mumbai = BOM, London = LHR)
Countries: 2-letter alpha code (e.g., India = IN, USA = US, UK = GB)
Flights: Airline code + flight number (e.g., 9W442 = Jet Airways Bangalore-Singapore at 2035 hrs)
C. Safety & Flight Operations
IATA Safety Audit (IOSA) for airlines. Air Traffic Management standards. Flight operations tools and business intelligence. Safety data and incident reporting systems.
D. Financial Services
BSP (Billing and Settlement Plan) — manages all financial transactions between airlines and accredited agents. CASS (Cargo Account Settlement System) for cargo. Financial solutions for airlines, airports, and travel professionals.
E. Training & Certification
IATA offers certification programmes in Air Ticketing, Cargo, Tourism, and Hospitality. IATA certifications are globally recognised credentials for aviation and travel professionals.
