Where Do You Depart From at ATL Airport?
The first thing to confirm before traveling to ATL is your airline’s departure location.
Atlanta Airport has a Domestic Terminal and an International Terminal, with flights operating through several concourses. Your airline and specific flight determine where you should check in and which gate you will use.
Because terminal and gate assignments can change, passengers should verify their flight information before leaving for the airport.
If you are unsure where to go, check your boarding pass, airline app, airport flight information, or ATL’s official information before entering the terminal.
ATL Domestic Departures
Passengers traveling on domestic flights generally begin their journey at the Domestic Terminal.
After entering the terminal, passengers should locate their airline’s check-in counters or self-service kiosks. Once check-in and baggage drop are completed, follow the signs toward the appropriate TSA security checkpoint.
After passing through security, passengers can use the Plane Train or walk to their assigned concourse depending on the location of their departure gate.
The domestic concourses include:
- Concourse T
- Concourse A
- Concourse B
- Concourse C
- Concourse D
Always confirm your gate number because the assigned concourse can vary by flight.
International Departures From Atlanta Airport
International passengers should carefully check their airline’s instructions before arriving at ATL.
International flights can operate through the International Terminal and associated concourses, including E and F. However, the exact check-in location and departure procedures depend on the airline and flight.
Passengers should allow additional time for:
- Airline check-in
- Passport and travel-document verification
- Checked baggage
- TSA security screening
- Walking or taking the Plane Train to the gate
- Additional airline boarding procedures
Travelers should also make sure their passport, visa, and other required travel documents are ready before reaching the airport.
How Early Should You Arrive for an ATL Departure?
The amount of time you need at Atlanta Airport depends on several factors.
Consider arriving earlier if you are:
- Checking baggage
- Flying internationally
- Traveling during a busy period
- Traveling with children
- Unfamiliar with ATL
- Parking at the airport
- Using rental-car transportation
- Connecting from another flight
Your airline may provide its own recommended arrival time, so check the instructions associated with your reservation.
It is also important to remember that getting to the airport terminal is only the first part of the journey. You still need enough time for check-in, baggage drop, TSA screening, transportation between concourses, and reaching your gate.
Check-In Process at ATL Airport
Most airlines provide several ways to check in before departure.
Online Check-In
If your airline allows online check-in, completing it before reaching ATL can save time. You may be able to access your boarding pass through the airline’s website or mobile application.
Airport Check-In Counters
Passengers who need assistance, are checking bags, or need document verification can visit their airline’s check-in counter.
Self-Service Kiosks
Some airlines provide self-service kiosks where passengers can print boarding passes or baggage tags.
Baggage Drop
If you have already checked in online, your airline may have a dedicated baggage-drop process. Follow the signs and instructions provided by the airline.
TSA Security at ATL Departures
After checking in and dropping your bags, the next major step is TSA security.
Atlanta Airport can experience significant passenger traffic, particularly during busy travel periods. Security processing time varies depending on passenger volume, staffing, time of day, and other operational factors.
Before entering the security line:
- Have your boarding pass ready.
- Keep your identification accessible.
- Follow TSA instructions regarding liquids and electronics.
- Remove or prepare items as required.
- Make sure you have all personal belongings before leaving the checkpoint.
TSA PreCheck and other eligible screening programs may provide different screening procedures for qualified passengers.
Finding Your ATL Departure Gate
Once you clear security, check the airport’s flight information screens for your latest gate assignment.
ATL has multiple concourses, and your gate may be a significant distance from the security checkpoint.
Look for signs directing you toward:
- Concourse T
- Concourse A
- Concourse B
- Concourse C
- Concourse D
- Concourse E
- Concourse F
The Plane Train is one of the easiest ways to travel between ATL’s concourses after security.
Using the Plane Train Before Your Flight
The Plane Train operates within the airport’s secure area and connects the concourses.
If your gate is located in a different concourse, follow the signs to the nearest Plane Train station.
For example, a passenger who clears security and discovers that their gate is several concourses away can use the Plane Train rather than walking the entire distance.
Even when using the train, leave enough time to:
- Find the correct station
- Travel to the appropriate concourse
- Locate your gate
- Complete any required boarding procedures

Passengers driving to the airport have several parking choices.
Your choice may depend on how long you plan to leave your vehicle at ATL and how close you want to be to the terminal.
Common parking categories include:
- Hourly parking
- Daily parking
- Economy parking
- Park-Ride options
- Other airport parking facilities
Before leaving home, check current airport parking information and availability, particularly during holidays and other high-demand travel periods.

Check your flight before leaving home:
Gate and operational information can change, so check the latest flight information.
Know your terminal:
Confirm whether your airline and flight require the Domestic or International Terminal.
Arrive with enough time:

Complete online check-in when available:
This can reduce the amount of time spent at airline counters.

Check your gate after security:
Do not assume the gate shown earlier will remain unchanged.
Use the Plane Train when appropriate:
It can save time when your departure gate is in another concourse.
ATL Airport Departures for Connecting Travelers
If ATL is your connecting airport, your departure process can be different from that of a passenger beginning their journey in Atlanta.
First, determine your next flight’s departure gate. Then check whether you need to change concourses or complete additional security or document procedures.
Passengers staying inside the secure area can generally use the Plane Train to move between concourses.
If your connection requires you to leave the secure area, allow additional time to go through the necessary procedures before reaching your next gate.
Food, Lounges and Amenities Before Departure
Passengers who arrive at ATL early can find a wide range of airport amenities throughout the terminals and concourses.
Depending on your location, you may find:
- Restaurants
- Cafes
- Fast-food options
- Retail stores
- Airport lounges
- Charging areas
- Restrooms
- Information services
- Accessibility facilities
Your airline or travel class may determine whether you have access to a particular lounge.
Because ATL is a large airport, it is generally better to check your gate location before spending too much time away from the departure area.

If your departure is delayed, check the latest information through your airline and airport flight displays.
A delay can result in:
- A new departure time
- A gate change
- A different aircraft
- A revised boarding time

If you have a connecting flight, contact your airline as soon as possible if a delay could affect your itinerary.
