When we think about airports, the first thing that comes to our mind is usually the airport terminal. However, there are different ways to refer to this central building where passengers depart and arrive. For instance, you might hear it called the airport concourse which refers to the open area where you have a direct access to the boarding gates. The airport gate area is where passengers wait for their flights to be called, while the terminal building encompasses all areas of the airport including check-in counters, baggage claim area, and restaurants and shops. Additionally, the airport lounge is a luxurious option designed for frequent flyers who want to relax and wait for their flights in a more comfortable and private environment.
