International Air Transport Association

International Air Transport Association (IATA)

The International Air Transport Association (IATA) is a global trade association representing the world’s airlines. Headquartered in Montreal, Canada, with executive offices at the Geneva Airport in Switzerland, IATA advocates for airline safety, environmental responsibility, efficiency, and standardization. Today, it represents approximately 240 airlines, accounting for over 84% of scheduled international air traffic.

What Does IATA Do?

IATA plays a central role in shaping commercial aviation policies and technical standards. Its primary functions include:

• Establishing global technical and operational standards for airlines
• Managing financial systems like the Billing and Settlement Plan (BSP)
• Assigning and regulating IATA airport and airline codes
• Operating the IATA Operational Safety Audit (IOSA)
• Promoting sustainable aviation fuel (SAF), emissions reduction, and carbon offset programs

Historical Background

Founded in 1945, IATA was created to unify the global airline industry following World War II. It succeeded an earlier version based in The Hague and rapidly became the leading organization for aviation governance alongside the International Civil Aviation Organization (ICAO).

In its early years, IATA standardized:

• Aircraft cockpit layouts
• Fire safety protocols
• Revenue accounting systems
• Ticketing and baggage handling procedures
• Flight schedules and international air routes

Modern Role in Aviation

IATA continues to influence commercial and private aviation globally. Key initiatives include:

• Airport slot coordination and scheduling
• Passenger self-service tools and digital boarding programs
• Cargo logistics, customs documentation, and electronic air waybills (e-AWB)
• Supporting workforce development and training through IATA Training

IATA Codes and Their Use

One of IATA’s most visible contributions is its 3-letter airport and 2-letter airline code system, used globally in flight bookings, boarding passes, baggage tags, and airline operations.

For example:

• LAX – Los Angeles International Airport
• JFK – John F. Kennedy International Airport
• SFO – San Francisco International Airport
• BA – British Airways
• DL – Delta Airlines
