The Air Transport Association (ATA) is a trade organization that represents the airline industry in the United States. Founded in 1936, it advocates for policies that promote the interests of its member airlines, which include major carriers and regional airlines. The ATA focuses on issues such as safety, security, and environmental sustainability in air travel. In 2012, the ATA rebranded itself as the Airlines for America (A4A) to better reflect its mission and the evolving airline industry. The organization provides valuable data and research on air transport trends, helping to inform both policymakers and the public about the importance of air travel to the economy and society.
