Is LAX Bigger Than Atlanta Airport? What Atlanta Travelers Should Know

If you live in Atlanta or fly through Hartsfield–Jackson Atlanta International Airport (ATL) often, you’ve probably heard people compare it to Los Angeles International Airport (LAX) and wonder: “Is LAX bigger than Atlanta airport?”

The short answer:
LAX covers more physical land area, but Atlanta’s airport is typically busier and handles more passengers and flights.

Below is a clear breakdown of what “bigger” really means and how this affects your travel in and out of Atlanta.

What Do We Mean by “Bigger”?

When people ask if LAX is bigger than Atlanta’s airport, they may mean several different things:

• Land area (how much physical space the airport takes up)
• Number of passengers (how many travelers move through the airport)
• Number of flights (takeoffs and landings)
• Number of runways and terminals

ATL and LAX trade places depending on which of these you’re talking about, so it helps to separate them.

Land Size: LAX Is Larger in Physical Area

In terms of pure physical size, LAX is generally considered larger than ATL. It spreads out over more land and has a more spread-out layout.

By comparison, Atlanta’s airport uses its space very efficiently. Much of ATL’s activity is concentrated around:

• One central domestic terminal split into North and South
• The International Terminal (Maynard H. Jackson Jr. International Terminal)
• A series of parallel concourses (T, A, B, C, D, E, F) connected by the underground Plane Train

So, if you’re only talking about acres or square miles, LAX is bigger on the map.

Passenger Traffic: ATL Is Usually Busier Than LAX

When travelers call ATL “big,” they often mean busy, not just physically large.

Hartsfield–Jackson Atlanta International Airport is consistently one of the busiest airports in the world by passenger volume. It regularly handles:

• Very high numbers of connecting passengers (people changing planes in Atlanta)
• Heavy daily domestic traffic across the U.S.
• A large number of international flights, especially through Concourse F and the International Terminal

LAX is also extremely busy, especially for:

• Transpacific flights to and from Asia and the Pacific
• International routes to Europe and Latin America
• Major domestic flights along the U.S. West Coast

But in many typical years, ATL handles more total passengers and often more flights than LAX. This is why, from an Atlanta perspective, people proudly say “Atlanta has the world’s busiest airport.”

So:

• Land size: LAX tends to be larger
• Passenger traffic and operations:ATL is often busier

Runways and Terminals: How ATL Compares to LAX

Both airports are large and complex, but they’re laid out differently, which you’ll definitely feel when you’re walking between gates or changing terminals.

Runways

• Atlanta (ATL):

  • Has multiple parallel runways running east–west
  • Designed for high-volume, efficient operations and frequent takeoffs/landings
  • This setup helps ATL move huge numbers of flights smoothly

• Los Angeles (LAX):

  • Also has parallel runways, but arranged differently along the north and south sides of the terminal area
  • Serves a high volume of long-haul flights, including many large international jets

From a traveler’s standpoint in Atlanta, the key takeaway is that ATL’s runway system is optimized for high frequency and reliability, which helps keep flights moving despite heavy traffic.

Terminals and Concourses

ATL’s layout (what you feel as a traveler in Atlanta):

• Domestic Terminal North & South (check-in for most U.S. flights)
• International Terminal (Concourse F) on the eastern side of the airport
• Concourses T, A, B, C, D, E, F connected in a straight line
• An underground Plane Train linking all concourses and terminals quickly
• A long central passenger connector tunnel with moving walkways

LAX’s layout:

• Multiple separate terminals arranged in a U-shaped loop
• More walking between terminals, often outdoors or via shuttle buses
• International flights typically use the Tom Bradley International Terminal (Terminal B) along with some other gates

If you’re used to Atlanta’s centralized concourses and quick inter-concourse train, LAX may feel more spread out and less unified, even though both airports are large.

“Busiest” vs. “Biggest”: Why Atlanta’s Airport Feels So Large

For Atlanta residents and visitors, ATL can feel bigger than LAX even though LAX may cover more ground. That’s because:

• More connecting flights: A huge share of passengers are changing planes in Atlanta, filling concourses throughout the day.
• Constant movement: The concourses, Plane Train, and security checkpoints are almost always busy.
• Dense layout: ATL fits a lot of gates and activity into a more compact footprint compared to LAX.

So while LAX may be larger in acreage, Atlanta’s airport often feels “bigger” in terms of energy, crowds, and activity.

Side‑by‑Side: ATL vs. LAX at a Glance

What This Means for You as an Atlanta Traveler

If you’re comparing airports because you’re planning a trip from Atlanta to Los Angeles or beyond, here’s how it matters in real life.

1. Connecting Through ATL vs. LAX

If you live in metro Atlanta (whether in the city, College Park, East Point, or the northern suburbs), connecting through ATL is usually more convenient:

• Shorter transfer times thanks to the Plane Train and linear layout
• Familiar signage and flow if you fly from ATL often
• Plenty of domestic and international options in one mega-hub

Connecting through LAX can involve:

• Moving between separate terminals
• Occasional shuttle rides or longer walks
• More spread-out services

If you’re used to Atlanta’s efficient connection experience, keep in mind that LAX may take a bit more time to navigate between flights.

2. Departing from Atlanta vs. Los Angeles

From an Atlanta departure perspective:

• Hartsfield–Jackson is directly accessible via:
  • MARTA rail (Airport Station at the Domestic Terminal)
  • I‑75, I‑85, and local surface streets
  • Rideshares, taxis, and shuttles
• Once inside, all concourses are connected behind security, so you don’t have to re-clear security to change concourses for most flights.

LAX, in contrast, typically requires:

• More car-based access using the freeway network or shuttles
• More time built in for inter-terminal changes if your airline uses multiple terminals

For most Atlanta-based travelers, ATL will feel more streamlined even if LAX physically covers more land.

3. International Travel From Atlanta

If you’re deciding between flying from ATL or connecting through LAX for an international trip, remember:

• ATL is a major international gateway on its own.
• You can reach Europe, parts of Africa, South America, and some Asian destinations directly from Atlanta, depending on airlines and schedules.
• The Maynard H. Jackson Jr. International Terminal (Concourse F) is purpose-built for:
  • Customs and immigration
  • Efficient transfers between international and domestic flights

You might only need LAX if:

• You are heading to specific Pacific or West Coast destinations that are better served through Los Angeles.
• Your airline’s network is centered on LAX for that route.

Practical Tips for Atlanta Flyers Comparing ATL and LAX

• Driving from downtown Atlanta:
  • Roughly 10–20 minutes in light traffic via I‑75/85 South, longer at rush hour.

Time to Allow at ATL vs. LAX

Every trip is different, but for most Atlanta travelers:

  • You may want a little extra buffer, especially if:
    • You need to change terminals
    • You’re checking bags and flying internationally

Choosing Routes From Atlanta

When booking from Atlanta, consider:

• If your airline offers a nonstop from ATL, you often avoid the extra complexity of connecting through LAX.
• For certain destinations in Asia or the Pacific, your itinerary may route through LAX, even if ATL is your home base.
• Because ATL is so busy and well-connected, many global routes are available directly or with just one connection that doesn’t involve LAX at all.

Bottom Line for Atlanta Travelers
