Regional aircraft are smaller airplanes designed to serve short-haul routes, typically connecting smaller cities to larger hubs. They usually have a seating capacity of 30 to 100 passengers and are optimized for efficiency and cost-effectiveness. These aircraft play a crucial role in regional transportation, making air travel accessible to areas that may not be served by larger airlines. Manufacturers like Bombardier and Embraer produce popular models of regional aircraft, such as the CRJ Series and E-Jets. These planes are often used by regional airlines and are essential for enhancing connectivity, reducing travel times, and supporting local economies.
