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. When purchasing airfare, travelers can find various options through travel agencies, airline websites, or online travel platforms. It's important to compare prices and consider additional fees, such as baggage charges, to understand the total cost of a flight.
