Airline charges refer to the fees and costs that airlines impose on passengers for various services, such as ticketing, baggage allowance, in-flight meals or entertainment, seat selection, and other additional services. These charges are in addition to the cost of the plane ticket itself and can vary depending on the airline, route, and class of travel. Airline charges help generate revenue for the airlines, but they can also add extra expenses for passengers, making it important for them to carefully consider their options when booking flights.
