An airport concourse is the airside section of the terminal building where passengers wait and board their flights. It is where the departure gates are located. The terminal is the larger main building that contains check-in desks, security checkpoints, baggage claim, and immigration , the full passenger processing infrastructure. The concourse is the extension of the terminal that you access after clearing security.
The two terms are frequently confused because in smaller airports they occupy the same building. In large international airports, the terminal and its concourses are distinct areas , often connected by walkways, trains, or shuttle buses , and understanding the difference helps you navigate more effectively and plan your time at the airport.
This guide explains what each area contains, how they relate to each other, and what the practical differences are for a passenger making their way from check-in to gate.
What is an Airport Terminal?
An airport terminal is the main building where passengers begin and end their journey through the airport. It is accessible from street level and handles all of the pre-flight processing that happens before you reach the departure gate.
The terminal is where you will find:
- Check-in counters and baggage drop. Airlines operate their check-in desks and baggage services here.
- Security screening. All passengers pass through security checkpoints in the terminal before entering the airside zone.
- Arrivals facilities. Baggage claim carousels, customs, and immigration are located in the terminal for passengers arriving from international flights.
- Ticketing and airline offices. Ground-level passenger services including rebooking and ticketing are handled in the terminal.
- Retail and food. Many terminals have shopping and dining areas on both the landside and airside levels.
Larger airports often have more than one terminal, each serving different airlines or a combination of domestic and international routes. Some airports use satellite terminals , separate structures connected to the main terminal by enclosed walkways or automated transit , to manage high passenger volumes.
What Is an Airport Concourse?
An airport concourse is the airside section of the terminal where departure gates are located. It is the part of the airport you access after clearing security. Once you are in the concourse, you are in the secure zone, you cannot re-enter the landside terminal without passing through security again.
The concourse is designed to manage the movement of large numbers of passengers to their departure gates. In most major airports, the concourse is a long corridor or pier extending from the terminal building, with gates running along each side. Each gate connects passengers to a jet bridge or boarding area that leads directly to the aircraft.
Concourses also typically contain:
- Departure lounges and seating areas at each gate.
- Restaurants, cafes, and retail shops for passengers waiting before boarding.
- Premium airline lounges, often accessible to business class passengers or lounge members.
- Duty-free retail in international concourses.
- Charging stations, Wi-Fi, and other passenger amenities.
In smaller airports, the terminal and concourse are one and the same building , check-in, security, and boarding gates all share a single space. In large international airports, a single terminal may connect to multiple concourses, each identified by a letter or number (Concourse A, Concourse B, and so on). Passengers moving between concourses may use walkways, moving walkways, underground trains, or shuttle buses depending on the airport layout.
Terminal vs Concourse: A Comparison
To make the distinction clearer, here is a side-by-side comparison of the key functions and features of an airport terminal and a concourse.
| Feature | Airport Terminal | Airport Concourse |
|---|---|---|
| Primary Function | Passenger processing (check-in, security, baggage claim) | Passenger waiting and boarding |
| Location | The main building connecting landside and airside | Airside (secure area), attached to the terminal |
| Key Facilities | Ticketing desks, check-in counters, security checkpoints, customs, baggage claim | Departure gates, waiting areas, passenger lounges |
| Passenger Flow | Manages both arriving and departing passengers | Primarily serves departing passengers |
| Amenities | Arrival/departure halls, airline offices, car rental counters | Retail shops, restaurants, duty-free stores, charging stations |
How Terminals and Concourses Work Together
The terminal and its concourses operate as a connected system. You enter the terminal from street level, check in, drop your bags, and pass through security. Once you clear security, you enter the airside zone , usually directly into a concourse or a connector that leads to one.
At large airports, the concourse you need will depend on your airline or departure gate. In airports like Hartsfield-Jackson Atlanta (ATL), which is the world’s busiest airport by passenger volume, a single terminal connects to five concourses (A through F, with T being the main terminal). Passengers travel between them on an underground automated train. At Chicago O’Hare (ORD), there are four terminals and multiple concourses within them. At Dubai International Airport (DXB), the airport uses the term “concourse” to describe its major departure buildings , Concourse A (Emirates), Concourse B, and Concourse C , each connected to the main terminal by an underground passenger mover.
Knowing your departure terminal and concourse before you arrive lets you plan your journey through the airport accurately. If your gate is in a concourse that requires a train or shuttle, allow an extra 10 to 15 minutes beyond your initial estimate.

Frequently Asked Questions (FAQs)
Q: Can a terminal have multiple concourses?
A: Yes, large airports often have one main terminal connected to several concourses. Passengers may use walkways, trams, or shuttle buses to move between the terminal and their departure concourse.
Q: Is the gate in the terminal or concourse?
A: The departure gate is located in the concourse. The concourse is the specific part of the airport building where passengers wait before boarding their flight at their assigned gate.
Q: Why do some airports only have a terminal and no separate concourse?
: Smaller airports with fewer gates often have a single building where check-in, security, and boarding gates are all located in one integrated area. In this case, the terminal building itself serves as the concourse.
Q: Are concourses always inside the secure area?
A: Yes, concourses are located “airside,” which means you must pass through a security checkpoint in the terminal to access them. All departure gates are situated within this secure zone.
Q: What does “concourse” mean in an airport?
A: In an airport, a concourse is the airside section of the terminal building where departure gates are located. The word comes from the Latin “concursus,” meaning a gathering or meeting place. In modern airport usage it refers specifically to the secure boarding zone , the corridor or structure you access after passing through security, which contains the gates, waiting areas, lounges, and retail spaces used by departing passengers.
Q: What is the difference between an airport concourse and an airport terminal?
A: The terminal is the main airport building , accessible from street level , where passengers check in, drop bags, and pass through security. The concourse is the airside extension of the terminal, accessible only after clearing security, where the departure gates and boarding areas are located. In large airports there is often one terminal and multiple concourses. In small airports, a single building serves as both.
Q: How do you get from the terminal to the concourse?
A: After checking in and passing through the security checkpoint, you enter the airside zone and typically arrive directly in or adjacent to a concourse. In airports where the concourses are separate structures from the main terminal, connections are usually made via an enclosed walkway, a moving walkway, or an automated train (called a people mover or automated transit system). The airport’s departure boards and signage will indicate which concourse and gate number corresponds to your flight.
Q: Can a flight change its concourse after I check in?
A: Yes. Gate and concourse changes do occur, most commonly due to aircraft swaps, operational delays, or terminal congestion. Your airline will typically send a notification via the app, email, or SMS if your gate changes. At the airport, departure boards are updated in real time and announcements are made over the public address system. If you are in a lounge or a distant concourse, check the departure board regularly in the final hour before boarding.
