Airlines for America

Airlines for America (A4A), formerly known as Air Transport Association of America (ATA), is America's oldest and largest airline trade association. A4A member airlines and their affiliates transport more than 90 percent of U.S. airline passenger and cargo traffic.

It is the only trade organization that represents the principal U.S. airlines and is their voice when lobbying Congress.
