Airfare refers to the price charged by airlines for transporting passengers from one location to another. This cost can vary based on several factors, including the distance of the flight, the time of booking, and the demand for seats. Airlines often offer different classes of service, such as economy, business, and first class, each with its own pricing structure. Airfare can also be influenced by seasonal trends, special promotions, and the overall competition among airlines. Travelers can find airfare through various platforms, including airline websites and travel agencies, which may offer tools to compare prices and find the best deals.
