A regional jet (RJ) is a jet-powered regional airliner typically designed to carry fewer than 100 passengers on short-haul flights. These aircraft are often used by regional airlines, which may operate independently or as subsidiaries contracted by larger carriers, to connect smaller markets to major airline hubs. Key manufacturers of regional jets include Embraer and Bombardier, with Embraer's E-Jet family being particularly popular. Regional jets play a crucial role in providing air service to communities that may not have sufficient demand for larger aircraft, facilitating connections within a country or a specific area of a continent.
