Airline regulation refers to the rules and policies established by governments to oversee the operation of airlines. These regulations ensure safety, security, and fair competition within the airline industry. They cover various aspects, including pricing, routes, and service quality, helping to protect consumers and maintain a stable market. In the United States, the Federal Aviation Administration (FAA) and the Department of Transportation (DOT) are key agencies involved in airline regulation. They enforce safety standards and manage air traffic, while also addressing issues like airline mergers and consumer rights. This regulatory framework aims to balance the interests of airlines, passengers, and the economy.
