Airlines are regulated through a complex multi-layered system of international, national, and regional authorities that ensure safety and fair competition in 2026. At the global level, the International Civil Aviation Organization (ICAO), a UN agency, sets the standards for safety, security, and environmental protection. Nationally, organizations like the Federal Aviation Administration (FAA) in the U.S. and the Civil Aviation Authority (CAA) in the UK govern pilot licensing, aircraft maintenance, and airspace management. Regionally, the European Union Aviation Safety Agency (EASA) harmonizes rules across Europe. Beyond safety, economic regulations are handled by departments like the U.S. Department of Transportation (DOT), which protects consumer rights regarding refunds and delays. Furthermore, the International Air Transport Association (IATA), while a trade group, plays a vital role in regulating the technical and commercial standards for the industry, such as baggage handling and ticketing systems, ensuring that travelers can move seamlessly between different airlines worldwide.
The Transportation Security Administration is an agency of the United States Department of Homeland Security that has authority over the security of transportation systems within, and connecting to the United States.
