An airport terminal is a building at an airport where passengers arrive and depart. It serves as the main hub for ticketing, check-in, security screening, and boarding. Inside, travelers can find amenities like shops, restaurants, and lounges to make their wait more comfortable. Terminals are designed to handle large volumes of people and often include multiple gates for different flights. Each terminal may serve specific airlines or destinations, and they are equipped with information displays to keep passengers updated on flight schedules and boarding times.
