What is a concourse in the context of an airport?

A concourse in an airport context refers specifically to the areas where flights arrive and depart. It typically includes gates from which passengers board or disembark aircraft. Concourses are crucial for the operational flow of an airport as they connect the terminal facilities to the aircraft parking areas. This space often features amenities such as seating, shops, and restaurants, providing travelers with comfort and convenience while they wait for their flights.

In contrast, the options related to baggage claim, check-in services, and customs processing refer to other distinct functions and areas within an airport. Baggage claim is where passengers retrieve their luggage after a flight. The check-in area is where travelers process their boarding documents and drop off checked baggage, while customs and immigration processing sections are designated for international travelers to declare items and obtain permission to enter a country. Each of these functions plays an important role in the travel experience, but they are not what defines a concourse.
