As of July 7, 2025, Hartsfield-Jackson Atlanta International Airport is in the middle of a major transformation. The airport, often called ATL, is the world’s busiest, serving more than 108 million passengers every year. Now, it’s investing billions of dollars in new technology, bigger spaces, and better systems to make travel smoother and more convenient for everyone. These changes are especially important as Atlanta prepares to welcome a surge of international visitors for the 2026 FIFA World Cup.
Let’s break down what’s happening at ATL, why it matters, and how these upgrades will affect travelers, airport workers, and the city of Atlanta.
Sweeping Upgrades for Traveler Convenience
The main goal behind all these projects is to boost traveler convenience. Whether you’re a frequent flyer, a first-time visitor, or someone arriving from another country, ATL wants your journey to be faster, easier, and less stressful. The airport is focusing on five big areas:
- The Plane Train system overhaul
- Concourse D expansion
- New customs and biometric technology
- Modernizing energy and power systems
- Improving how travelers connect between terminals and public transportation
Each of these projects brings its own set of changes, benefits, and challenges. Here’s what you need to know.
Plane Train System Overhaul: Faster, Greener, and More Reliable
The Plane Train is ATL’s underground people mover. It shuttles passengers between terminals and concourses, helping them catch flights and make connections quickly. Right now, the airport is spending $300 million to upgrade this system.
What’s Changing?
- More Trains: The fleet is growing from 59 to 73 vehicles, with 63 brand-new, energy-efficient cars.
- Higher Capacity: The new trains will be able to move up to 12,000 people per hour in each direction, up from 10,000.
- Shorter Waits: Passengers will wait just 90 seconds between trains, instead of the current 108 seconds.
- Better Experience: The trains will have clearer signs and more handholds, making rides safer and easier to understand.
- New Tunnel: A turnaround tunnel under the domestic terminal is now finished, letting trains run more smoothly and efficiently.
When Will It Be Ready?
The full Plane Train upgrade is expected to be finished by early 2026. Until then, travelers might notice some construction, but the airport is working to keep disruptions to a minimum.
Why Does This Matter?
For travelers, this means less time waiting and more time relaxing before your flight. If you’re connecting between international and domestic flights, the improved Plane Train will make those tight connections less stressful. According to analysis by VisaVerge.com, these upgrades are part of ATL’s push to stay ahead as the world’s busiest airport and to keep up with rising passenger numbers.
Concourse D Expansion: More Space, More Comfort
Concourse D is one of the busiest parts of ATL, often crowded with travelers waiting for flights. To fix this, the airport started a $1.3 billion expansion project in September 2023. The work is expected to finish in 2029.
Key Features of the Expansion:
- Wider and Taller: The concourse will grow from 60 to 99 feet wide, and ceilings will rise from 11 to 18 feet.
- Longer: The building will stretch an extra 288 feet.
- More Room to Wait: Hold rooms (where passengers wait to board) and restrooms will double in size.
- More Seats: There will be 1,000 more seats, bringing the total to 6,400.
- Fewer Gates, More Space: The number of gates will drop from 40 to 34, but each gate will have much more space for boarding and moving around.
How Is Construction Happening?
To avoid shutting down the whole concourse, the airport is using prefabricated modules built offsite. These are installed at night, and only eight gates are closed at a time. This keeps most of the concourse open for travelers.
Why Is This Important?
The expansion will help ATL handle bigger planes and more passengers. It also addresses long-standing problems with crowding and congestion, making travel more comfortable for everyone.
AI-Driven Customs and Biometric Processing: Faster Entry for U.S. Citizens
Getting through customs can be one of the slowest parts of international travel. ATL is now using new technology to speed up this process, especially for U.S. citizens.
What’s New?
- Facial Recognition Kiosks: Instead of showing your passport to an officer, you can use a kiosk that scans your face and matches it to your passport photo.
- Faster Processing: Since launching in May 2025, this system has cut wait times for U.S. citizens by 22%.
- High Accuracy: The system is 98% accurate and has helped catch more impostor passengers across the country.
- Portable Kiosks: These can be moved around based on flight schedules, making the system flexible.
- Opt-Out Option: If you don’t want your face scanned, you can ask for a manual inspection instead.
What Are the Concerns?
Some privacy groups, like the Electronic Privacy Information Center (EPIC), worry about how facial data is stored and used. They want the airport to be careful about privacy, bias, and surveillance risks.
Expert View:
Clay Thomas, the Customs and Border Protection (CBP) Atlanta Area Port Director, says the new system lets officers spend more time helping travelers and less time on paperwork.
How Does This Affect Travelers?
If you’re a U.S. citizen, you’ll likely get through customs faster. If you’re not comfortable with facial recognition, you still have the right to opt out. For more information about customs and entry requirements, you can visit the U.S. Customs and Border Protection official website.
Energy Infrastructure Modernization: Powering the Airport’s Future
Running the world’s busiest airport takes a lot of energy. ATL is working to make its power systems smarter, more reliable, and better for the environment.
What’s Happening?
- ATLNext Initiative: This is a $12.8 billion program to modernize everything from terminals to parking lots.
- Eaton Partnership: In June 2025, ATL gave Eaton a $25 million contract to upgrade the airport’s electrical systems.
- Smart Technology: Thousands of smart devices will monitor power use in real time and help fix problems before they cause delays.
- Sustainability: The goal is to create a strong, future-proof energy system that can handle new technology and more passengers.
Why Does This Matter?
For travelers, this means fewer power outages and smoother airport operations. For the environment, it means less wasted energy and a smaller carbon footprint.
Improving Terminal Connectivity and Ground Transportation
Getting from the airport to the city, or between different terminals, can be tricky—especially for international travelers. ATL is working with city and transit officials to make these connections easier.
Current Challenges:
- The International Terminal isn’t directly connected to MARTA, Atlanta’s main rail system.
- International arrivals often have to use shuttles or buses to reach MARTA stations, which can be confusing and slow.
Proposed Solutions:
- SkyTrain Extension: There are plans to extend the SkyTrain (an above-ground people mover) from the Domestic Terminal to the International Terminal. However, this won’t be ready before the 2026 World Cup.
- Dedicated MARTA Buses: The airport is looking at running special buses with space for luggage directly from the International Terminal to key MARTA stations.
- Luggage Recheck Options: Officials are exploring ways for international passengers to recheck their bags at Concourse F and use the Plane Train to reach the Domestic Terminal. Security and customs rules make this complicated, so it’s still under review.
Ongoing Efforts:
Airport, city, and MARTA officials meet every month to discuss ways to improve the traveler experience, especially with the World Cup on the horizon.
Preparing for the 2026 World Cup and Beyond
Many of these upgrades are being fast-tracked to get ready for the 2026 FIFA World Cup. Atlanta expects a huge increase in international visitors, and the airport wants to make sure it can handle the crowds.
Long-Term Vision:
Airport leaders and technology partners imagine a future where travelers can move through ATL almost seamlessly. Biometric and AI-driven systems could one day remove the need for traditional security and customs lines, making travel even faster and easier.
What Travelers Can Expect Right Now
While many projects are still underway, travelers will start to notice some immediate benefits:
- Shorter Waits: Both for the Plane Train and for customs, especially for U.S. citizens.
- Easier Navigation: Bigger concourses, better signs, and more seating make it simpler to find your way and relax.
- More Choices: Travelers can choose whether to use biometric screening or stick with manual checks.
- Ground Transit: For now, international arrivals should plan to use current shuttle and bus options to connect to MARTA.
Implications for Stakeholders
