AirlineAirportTerminals are the buildings inside airports where travelers can arrive and depart. Check-in counters, boarding gates, baggage claim rooms, security screening sections, and lounges, dining options, and retail stores are usually located in these terminals. In order to maintain passenger safety and comfort, terminals are built to manage the flow of people, luggage, and aircraft services effectively. Depending on the airport’s size and design, some terminals could be exclusively used by one airline or kind of aircraft (for example, local or international), while others house several airlines. In order to improve both operational efficiency and the travel experience for passengers, airport terminal design and functionality are crucial.
