Commercial aviation refers to the operation of aircraft for the purpose of transporting passengers and cargo. This sector includes airlines that provide scheduled flights, charter services, and cargo transport. Major airlines, such as American Airlines and Delta Air Lines, operate large fleets of aircraft to connect cities and countries around the world. The commercial aviation industry is regulated by government agencies, such as the Federal Aviation Administration (FAA) in the United States, which ensures safety and compliance with aviation standards. Airports serve as hubs for these operations, facilitating the movement of millions of travelers and goods each year.
