AirlineAirportTerminals usually contain baggage claim facilities, boarding gates, security screening sections, check-in counters, and lounges, dining options, and retail stores. While maintaining comfort and safety, terminals are made to manage the flow of people, luggage, and aircraft services effectively. Certain terminals may be devoted to particular airlines or flight types (such as domestic or international), while others house several carriers under one roof, depending on the airport's size and design.
