The Regional Airline Association (RAA) is a U.S. nonprofit 501(c)(6) trade association providing a unified voice for North American regional airlines and their industry partners. It advocates before Congress, the Federal Aviation Administration, the Department of Transportation, and other regulators for safe, reliable, and strong regional air service; supports members with policy analysis, safety and operational collaboration, conventions, purchasing forums, and shared best practices. RAA's regional carriers provide essential links to small communities and, in 2024, operated 32% of scheduled U.S. passenger flights and the only scheduled passenger service to nearly two-thirds of U.S. airports. RAA relocated its headquarters to 50 F Street NW, Suite 1200, Washington, DC, in 2025.
