Traveling through an airport can be a confusing experience with multiple terminals, concourses, and gates to navigate. If you’ve ever wondered what the different divisions of an airport terminal are and what purpose they serve, you’ve come to the right place.

In short, the main divisions of an airport terminal include the landside, airside, concourses, lounges, gates, and baggage claim. We’ll explore each of these sections in detail throughout this comprehensive guide.

Landside vs. Airside Areas

When it comes to airport terminals, there are two distinct areas that passengers need to be aware of: landside and airside. Understanding the difference between these areas can help you navigate the airport more efficiently and make your travel experience smoother.

Landside Areas

Landside areas in airports are the parts that are accessible to the general public, including passengers, visitors, and airport staff. These areas are located before the security checkpoints and include the check-in counters, ticketing areas, baggage claim, arrival and departure halls, waiting lounges, retail shops, restaurants, and other amenities.

Passengers usually spend a significant amount of time in landside areas, especially during check-in and baggage drop-off. This is where you can find information desks, customer service centers, and transportation options such as taxis, car rentals, and public transportation terminals.

Landside areas are also where passengers can meet and say goodbye to their loved ones before heading to the airside areas.

Airside Areas

Airside areas in airports are the secure areas accessible only to passengers who have cleared the security checkpoints. These areas are where the boarding gates, departure lounges, duty-free shops, and airline lounges are located.

Once passengers enter the airside areas, they are no longer able to return to the landside areas without going through security screening again.

Airside areas are designed to provide passengers with a comfortable and convenient experience while they wait for their flights. These areas often have a wider range of amenities compared to landside areas.

Passengers can enjoy duty-free shopping, grab a bite to eat at a restaurant or café, or simply relax in the lounge areas before their flight.

Security Checkpoints

Security checkpoints play a crucial role in separating landside and airside areas. These areas are where passengers and their belongings go through screening processes to ensure the safety and security of air travel.

Security checkpoints are equipped with X-ray machines, metal detectors, and other screening equipment to detect prohibited items.

Passengers are required to remove their shoes, jackets, and belts, and place their carry-on bags and personal items in bins for X-ray scanning. Liquids, gels, and aerosols must be in containers of 3.4 ounces (100 milliliters) or less and placed in a clear, resealable plastic bag.

Security personnel also conduct random or targeted pat-down searches if necessary.

It’s important to arrive at the airport with enough time to go through security checkpoints, as the process can sometimes be time-consuming, especially during peak travel seasons. Being prepared and following the guidelines set by the Transportation Security Administration (TSA) or relevant airport authorities can help expedite the process and ensure a hassle-free journey.


When navigating through an airport terminal, one of the key areas you will encounter is the concourse. These sections of the terminal are designed to accommodate passengers as they wait for their flights or move between connecting flights.

Concourses are an essential part of the airport infrastructure, providing various amenities and services to ensure a smooth travel experience for passengers.

Purpose and Layout

The primary purpose of a concourse is to facilitate the movement of passengers between different areas of the terminal and provide them with essential services. Typically, concourses are located perpendicular to the main terminal building, extending outwards like arms.

This layout allows for efficient separation of arriving and departing passengers, minimizing congestion and ensuring a seamless flow of people.

Concourses are typically equipped with a range of amenities to enhance the passenger experience. These may include comfortable seating areas, restrooms, food and beverage outlets, duty-free shops, and other retail establishments.

Many modern concourses also feature charging stations for electronic devices, Wi-Fi access, and even entertainment options like art installations or live performances.

Types of Concourses

There are different types of concourses that can be found in airport terminals, each serving a specific purpose. One common type is the main concourse, which acts as the central hub connecting various gates and boarding areas.

This is where passengers typically wait before boarding their flights and where they can find a variety of services and amenities.

In addition to the main concourse, airports may also have satellite concourses. These are separate sections of the terminal that are connected to the main concourse via underground tunnels or skybridges.

Satellite concourses are often used for specific airlines or flight destinations, allowing for more efficient operations and reducing congestion in the main concourse.

Another type of concourse is the international concourse, which is dedicated to flights arriving from or departing to international destinations. These concourses usually have additional security measures in place, such as passport control and customs checkpoints, to ensure compliance with immigration and customs regulations.

It is important to note that the layout and types of concourses may vary between airports. Some airports may have multiple concourses serving different airlines or flight alliances, while others may have a single concourse that caters to all flights.

The design and amenities of concourses also evolve over time as airports strive to provide better experiences for their passengers.

To learn more about airport concourses and their layouts, you can visit reputable sources such as the Airports Council International or specific airport websites that provide detailed information on their facilities.


When it comes to airport lounges, there are several premium options available for travelers looking to enhance their airport experience. These lounges provide a comfortable and relaxing environment, away from the hustle and bustle of the main terminal.

Here are some of the top lounges that you can find in various airport terminals:

Admiral’s Club

The Admiral’s Club, operated by American Airlines, is a popular lounge option for frequent flyers. With its spacious seating areas, complimentary snacks and beverages, and access to Wi-Fi, it offers a great place to unwind before your flight.

The lounge also provides business amenities, such as workstations and meeting rooms, for those who need to catch up on work.

Delta Sky Club

Delta Sky Club is another well-known lounge that can be found in many airport terminals. This lounge offers a range of amenities including comfortable seating, a variety of food and beverage options, and access to charging stations.

Travelers can also enjoy Wi-Fi access, private restrooms, and even showers in some locations.

United Club

United Club is the lounge option provided by United Airlines. It offers a relaxing atmosphere with comfortable seating, complimentary snacks and beverages, and access to Wi-Fi. Travelers can also take advantage of business amenities, such as workstations and conference rooms, making it a convenient option for business travelers.

American Express Centurion Lounge

The American Express Centurion Lounge is an exclusive lounge available to American Express cardholders. It offers a luxurious experience with high-end amenities, including gourmet dining options, premium cocktails, and spa services.

The lounge also provides a variety of seating areas, from comfortable loungers to private workspaces, catering to different traveler needs.

It’s important to note that access to these lounges may vary depending on factors such as airline loyalty status, ticket class, and membership programs. Some lounges may require a separate fee or a specific credit card membership.

It’s always a good idea to check the specific requirements and availability beforehand to make the most of your airport lounge experience.


Gate Types

When you arrive at an airport terminal, you will notice that it is divided into different gates. These gates serve as designated areas where passengers board and disembark from their flights. There are several types of gates that you may encounter:

  • Domestic Gates: These gates are used for flights within the same country. They are typically located in a separate area from international gates and are often assigned to specific airlines or airline alliances.
  • International Gates: These gates are used for flights that are departing or arriving from another country. They are equipped with additional facilities such as customs and immigration checkpoints to handle international passengers.
  • Regional Gates: These gates are used for flights to and from neighboring or nearby countries. They are often smaller in size and may have fewer amenities compared to international gates.
  • Remote Gates: These gates are located away from the main terminal building and require passengers to be transported by shuttle bus or aircraft stairs to board or disembark from their flights. They are commonly used in airports where space is limited or when there is a high volume of flights.
  • Jet Bridge Gates: These gates are equipped with jet bridges, which are enclosed walkways that connect the terminal building to the aircraft. Passengers can board and disembark directly from the terminal without having to go outside.

Boarding Process

Once you have passed through security and reached your designated gate, it’s time to board the aircraft. The boarding process is typically divided into different zones or groups to ensure an organized and efficient flow of passengers. Here is a general overview of the boarding process:

  1. First Class and Priority Boarding: Passengers with first-class tickets or those who have elite status with the airline are usually the first to board. They are given priority access to the aircraft.
  2. Zone Boarding: The remaining passengers are divided into different zones or groups, which are usually indicated on their boarding passes. Passengers in each zone are called to board the aircraft one group at a time.
  3. General Boarding: Once all the priority and zone passengers have boarded, general boarding begins. Passengers without assigned seats or those who checked in late typically fall into this category.

The boarding process may vary slightly depending on the airline and airport, so it’s always a good idea to listen for announcements or check with airport staff for specific instructions.

Baggage Claim

Domestic vs. International

When it comes to baggage claim, there are some key differences between domestic and international flights. For domestic flights, passengers typically retrieve their checked baggage in the same terminal they arrived in.

However, for international flights, passengers may have to go through customs and immigration before picking up their luggage. This means that the baggage claim area for international flights is often located in a separate section of the terminal.

It’s important for travelers to be aware of these differences and follow the signs and instructions provided at the airport to ensure a smooth baggage claim process.

Baggage Carousels

Once passengers have cleared customs (if applicable), they will make their way to the baggage claim area. This is where they can expect to find a series of baggage carousels rotating with suitcases and bags.

Baggage carousels are typically labeled with flight numbers or airline names to help passengers locate their luggage.

Passengers should keep their baggage claim ticket handy as it will have important information such as the carousel number and any unique identifiers for their luggage. It is advisable to double-check the information on the ticket to ensure they are waiting at the correct carousel.

While waiting for their luggage, passengers can take advantage of the amenities available in the baggage claim area, such as restrooms, seating areas, and even shops or cafes. This can help make the wait more comfortable and enjoyable.

Lost Luggage

Although rare, there is always a possibility that luggage may go missing during the baggage claim process. If a passenger’s luggage does not appear on the carousel or is damaged upon retrieval, it is important to immediately report the issue to the airline’s baggage service office.

The airline staff will assist in filing a claim and providing necessary documentation to track down the missing luggage. It is advisable for passengers to provide a detailed description of their luggage and any unique identifiers to help with the search process.

In the unfortunate event that luggage is lost, airlines usually have a process in place to compensate passengers for their belongings. It is important to keep receipts for valuable items and to check the airline’s policies regarding lost luggage.

For more information on baggage claim and lost luggage, passengers can visit the official website of the airport they are traveling through or refer to the airline’s website for specific procedures and contact information.


Now that you’re familiar with the various sections and facilities that make up an airport terminal, navigating these massive transportation hubs will feel much less daunting. Understanding the general layout and purposes of landside vs. airside areas, concourses, lounges, gates, and baggage claim will help you get to your flight with minimal stress and confusion.

Safe travels!
