An airport terminal is a building where passengers arrive and depart for their flights. It serves as a hub for various services, including ticketing, baggage claim, and security checks. Terminals are designed to facilitate the smooth flow of travelers, providing amenities like shops, restaurants, and lounges. Each terminal is typically divided into different areas, such as check-in counters, boarding gates, and customs. Airports may have multiple terminals, each serving different airlines or destinations. The layout and facilities can vary significantly between international airports and domestic airports, catering to the needs of travelers.
