What Hartsfield-Jackson Atlanta is and where it sits

Hartsfield-Jackson Atlanta International Airport (ATL) is the busiest airport in the world by passenger volume. It sits about 10 miles south of downtown Atlanta, Georgia, and handles flights for most major U.S. and international carriers. The airport has two terminals — the main terminal and the domestic terminal — connected by the airport's train system.

The airport serves as a major hub for Delta Air Lines, which operates the largest number of flights there. If you are flying through Atlanta, you may land at ATL even if Atlanta is not your final destination. Understanding the layout and services at this airport helps you move through it faster and find what you need.

Key Takeaways

  • Hartsfield-Jackson Atlanta has two terminals connected by an automated train, and most domestic flights use the domestic terminal while international flights use the main terminal.
  • The airport's train system runs 24 hours and moves between terminals, the parking decks, and the rental car facility at no charge.
  • TSA PreCheck and CLEAR lanes operate at ATL, and both can reduce time spent in security screening.
  • Ground transportation options include rental cars, rideshare services, MARTA public transit, and taxi stands, each with different costs and wait times.
  • The airport has restaurants, shops, and services throughout both terminals, though prices are higher than outside the airport.

The two terminals and how to move between them

The domestic terminal handles most flights within the United States. The main terminal handles most international flights and some domestic ones. Both terminals have security checkpoints, gates, and passenger services, but they are separate buildings.

An automated train called the Plane Train connects the two terminals, the parking decks, and the rental car facility. The train runs 24 hours a day and costs nothing to ride. Trains arrive every few minutes during the day and every 10 to 15 minutes late at night. If you are changing planes and your connection requires moving between terminals, follow the signs for the Plane Train or ask an airport employee for directions.

Walking between terminals is not practical — the distance is too far. Use the train instead. If you arrive at one terminal but your next flight leaves from the other, allow at least 90 minutes for a domestic connection and two hours for an international connection, since you will need to collect baggage, recheck it, and pass through security again.

Security screening and TSA PreCheck

All passengers must pass through a TSA security checkpoint before reaching the gates. Lines are longest in the early morning (5 a.m. to 8 a.m.) and early evening (4 p.m. to 7 p.m.). Both terminals have multiple checkpoints, and the airport displays wait times on screens near the entrances.

TSA PreCheck is a program that lets you move through a faster security lane if you have been vetted in advance. It costs $78 to $85 for five years and requires an in-person appointment at an enrollment center. If you hold TSA PreCheck, you can keep shoes, belts, and light jackets on, and you can leave laptops and liquids in your bag. At ATL, TSA PreCheck lanes operate in both terminals.

CLEAR is a separate service that uses biometric scanning (your eyes and fingerprints) to move you to the front of the security line. It costs around $189 per year and requires enrollment at an airport kiosk or online. CLEAR does not replace security screening — it just gets you to the checkpoint faster. Both TSA PreCheck and CLEAR operate at Hartsfield-Jackson.

Getting to and from the airport

Several ways to reach ATL exist, and the best choice depends on where you are coming from, how many people are traveling, and your budget.

MARTA public transit is the cheapest option. MARTA is Atlanta's public train system, and a dedicated rail line runs directly into the airport. A one-way ticket costs $2.50, and trains run every 10 to 15 minutes during the day and every 20 minutes late at night. MARTA reaches downtown Atlanta and other parts of the city. Travel time from downtown to the airport is about 40 minutes. MARTA does not serve the airport 24 hours — service ends around midnight and resumes around 5 a.m.

Rideshare services like Uber and Lyft operate at ATL. Pickup zones are clearly marked in both terminals. Prices vary based on demand and distance, but a ride to downtown Atlanta typically costs $15 to $30. During peak travel times, surge pricing can double or triple the fare. Wait times are usually 5 to 15 minutes.

Rental cars are available from major companies (Enterprise, Hertz, Avis, Budget, and others) in a dedicated facility connected to the airport by the Plane Train. Rental rates vary widely by company, car type, and season. You will need a valid driver's license and a credit card. The rental facility is open 24 hours.

Taxi stands operate in both terminals. Taxis charge a flat rate of $30 to downtown Atlanta, set by the city. Wait times can be 15 to 30 minutes during busy periods. Taxis are available 24 hours.

Parking at Hartsfield-Jackson

If you are driving to the airport, several parking options exist. Short-term parking is the most expensive and is meant for quick drop-offs or brief stays. Long-term parking costs less per day but is farther from the terminals. Economy parking is the cheapest option and requires a shuttle bus to reach the terminal.

Rates change based on demand and season. During holidays and peak travel times, parking fills up and prices rise. You can reserve parking online in advance through the airport's website, which sometimes offers discounts compared to paying at the gate. All parking decks are connected to the terminals by the Plane Train.

Restaurants, shops, and services in the terminals

Both terminals have restaurants, cafes, shops, and services throughout the concourses. Options include national chains (McDonald's, Chick-fil-A, Starbucks), local Atlanta restaurants, bookstores, electronics shops, and duty-free stores. Prices are higher than you would pay outside the airport — a sandwich might cost $14 to $18, and a coffee might cost $5 to $7.

Both terminals have charging stations for phones and laptops, family restrooms, nursing rooms, and prayer rooms. Free Wi-Fi is available throughout the airport. ATMs and currency exchange services operate in both terminals. If you need help, airport information desks are located in both terminals and staffed during operating hours.

Frequently Asked Questions

How early should I arrive at Hartsfield-Jackson before my flight?

For domestic flights, arrive two hours before departure. For international flights, arrive three hours before departure. These times assume normal security lines. During holidays or peak travel periods, arrive an extra 30 minutes early. If you have TSA PreCheck or CLEAR, you may be able to arrive 30 minutes later.

Can I bring food and drinks through security?

Solid foods like sandwiches, fruit, and snacks can pass through security. Liquids and gels — including peanut butter, yogurt, honey, and soups — cannot. You can buy food and drinks after you pass through security and bring them on the plane.

What should I do if I have a tight connection between terminals?

Tell a gate agent or airport employee about your tight connection as soon as you land. They can direct you to the fastest route and may be able to hold your next flight if you are running late. Use the Plane Train to move between terminals — it is faster than walking. Have your boarding pass ready before you board the train.

Is there a hotel at the airport?

No hotel is inside the terminals, but the Plane Train connects to a hotel facility in the airport area. Hotels near the airport are a short train ride away. If you need a place to rest between flights, some airlines offer day rooms or lounge access for passengers with premium tickets.

Does Hartsfield-Jackson have 24-hour services?

The airport itself operates 24 hours, and rental cars, taxis, and some restaurants stay open around the clock. However, MARTA public transit does not run late at night — service ends around midnight and resumes around 5 a.m. Some shops and restaurants close late evening and reopen early morning.
