An airport terminal is a building at an
airport where passengers transfer between ground transportation and the facilities that allow them to board and disembark from
airplanes.Passengers taking a flight will typically take an
automobile,
taxi,
bus, or
train to the airport and then enter the terminal. Within the terminal, passengers purchase tickets, transfer their luggage, and go through security. The buildings that provide access to the airplanes (via
gates) are typically called concourses. However, the terms "terminal" and "concourse" are sometimes used interchangeably, depending on the configuration of the airport.
