Allairportsterminals are designated locations within airports where passengers can board and disembark, check in for flights, go through security, and access other services. These terminals usually have a lot of gates, airline lounges, duty-free stores, restaurants, waiting areas, and baggage claim areas. There may be one or many terminals, each serving a different airline, flight path, or form of transit (domestic or international), depending on the size of the airport. The purpose of terminal layouts is to make the journey convenient and pleasurable for passengers by facilitating their movement from check-in to boarding.
