Tens of millions of passengers pass through these terminals every year, and what’s waiting inside will genuinely surprise you. Whether the airport you’re flying through lands on this list or not, you need to know what’s coming.
America’s airports are not all created equal. Some are cities unto themselves, sprawling across more land than Manhattan. Others have reinvented themselves entirely, swapping dingy food courts for James Beard-caliber chefs and speakeasy lounges.
Based on the latest 2025 passenger data from the Bureau of Transportation Statistics, these are the 20 busiest airports in the United States ranked by the number of passengers who boarded commercial aircraft, plus everything worth knowing before your next layover.
1. Hartsfield-Jackson Atlanta International Airport, ATL (51.45 million passengers)
Atlanta holds the top spot. Not just in the U.S., but in the entire world.
Hartsfield-Jackson Atlanta International Airport sits ten miles from downtown and handles its enormous passenger load across a 6.8 million-square-foot terminal complex with 152 domestic gates and 40 international gates.
It is Delta Air Lines’ home base, which means lounge access is generous. Every one of the seven concourses (A, B, C, D, E, F, and T) has at least one Delta Sky Club, plus an American Airlines Admirals Club, a United Club, and the Club at ATL for Priority Pass holders.
In 2023, Atlanta also unveiled a PS private suite terminal for passengers who want a truly exclusive pre-flight experience.
The dining scene punches well above what you would expect from an airport.
There are more than 100 food and beverage options, with highlights including One Flew South in Concourse E, an acclaimed upscale American restaurant; Shake Shack in Concourse A; Original El Taco in Concourse C for inventive Mexican; and Ludacris’ Chicken and Beer in Concourse D for Southern comfort food.
An ambitious rotating art program means there is always something worth stopping to look at between gates.
2. Dallas Fort Worth International Airport, DFW (41.29 million passengers)
DFW spans 26 square miles across five terminals and 168 gates, making it larger than the entire island of Manhattan, and it even has its own zip code.
Despite the scale, the airport is pushing hard toward sustainability. It is on track to achieve net-zero carbon emissions by 2030, backed in part by a $35 million federal grant for a zero-carbon electrical plant.
Lounge options include American Airlines Flagship First and Admirals Clubs, a Delta Sky Club, Capital One Lounge, Centurion Lounge, and the Club at DFW for Priority Pass holders.
A Plaza Premium Lounge opened in Terminal D in February 2026 and ranks among the best new airport lounges in the country.
For food, Terminal B has Cousins Bar-B-Q for smoked meats and sides, Terminal C has a Shake Shack, and Terminals D and E are home to Fort Worth coffeehouse Brewed.
3. Chicago O’Hare International Airport, ORD (40.67 million passengers)
O’Hare is Chicago’s main global hub, with more than 200 gates spread across four terminals (1, 2, 3, and 5 — there is no Terminal 4).
Lounges include an American Airlines Flagship Lounge and Admirals Club, a Delta Sky Club, and a United Club and Polaris Lounge.
It also has some genuinely thoughtful amenities. Terminal 3 has a yoga room and urban garden for pre-flight calm, Terminal 2 has a family lounge with a play area near gate F1, and all four terminals have nursing rooms.
Food highlights include three locations of chef Rick Bayless-backed Tortas Frontera (in Terminals 1, 3, and 5) and Wicker Park Seafood and Sushi Bar in Terminals 1 and 2.
4. Denver International Airport, DEN (39.98 million passengers)
Denver International Airport has 172 gates, 90 of which are operated by United Airlines, the airport’s dominant carrier.
The terminal’s iconic tent-like peaked roof architecture is immediately recognizable, and the art collection spread throughout the building is genuinely worth a wander before boarding.
During the holiday season from mid-November through early January, an ice skating rink and live music set up in the outdoor plaza.
Lounge options include an American Airlines Admirals Club, an Amex Centurion Lounge, a Delta Sky Club, a supersized United Club that reopened in 2025 after a full overhaul, and a new United Club Fly concept for travelers who need a quick in-and-out.
In Concourse A, Breckenridge Brewery pours local craft beers and Brothers BBQ serves serious sandwiches. Head to Concourse B for a proper breakfast at Snooze, or Concourse C for something sweet from Little Man Ice Cream.
5. Los Angeles International Airport, LAX (36.48 million passengers)
LAX offers 161 gates across nine passenger terminals and is in the middle of a major transformation, including the near-opening of an electric rail People Mover system that will finally give the airport real public transit access.
The dining situation has improved dramatically in recent years. Standouts include inventive burgers at Umami Burger and creative Mexican food at Border Grill, both in the Tom Bradley International Terminal, which also has a surf-themed play area for kids.
Every major U.S. carrier has a lounge at LAX, alongside several international airlines, credit card companies, and alliance network clubs.
6. John F. Kennedy International Airport, New York (JFK) (30.76 million passengers)
JFK is mid-transformation, and that transformation is a big one. A $19 billion revamp slated for completion in 2030 will reduce the current six terminals to four, anchored by two new complexes at either end of the airport.
Terminals 2 and 7 are set to be demolished as part of the project. A new Terminal 1 will serve Air France, Lufthansa, and others, and will eventually connect to an expanded Terminal 4, home to Delta. A new Terminal 6 will serve JetBlue.
Terminal 8 unveiled its makeover in April 2026, expanding by 130,000 square feet to add five new gates, dozens of new dining and retail options, and an improved baggage system. American Airlines, British Airways, and other Oneworld partners are the primary tenants.
If there is time to spare, the Eero Saarinen-designed TWA Flight Center is a must-see.
It has been transformed into the TWA Hotel, a nostalgia-filled shrine to 1960s glamour, with the Paris Café by Jean-Georges serving cuisine inspired by vintage in-flight menus, a casual Food Hall, the iconic Sunken Lounge, and a vintage Lockheed Constellation prop plane parked outside that now operates as a cocktail bar.
7. Orlando International Airport, MCO (27.9 million passengers)
Orlando draws tens of millions of theme park pilgrims every year, and the airport reflects that energy. Numerous gift shops throughout the terminal sell merchandise from Walt Disney World and Universal Orlando, making it easy to grab any souvenirs left behind during the rush of rides.
Terminal C, which opened in 2022, serves JetBlue, Aer Lingus, British Airways, Emirates, and Lufthansa, among others, and brought strong new dining options including Sunshine Diner by chef Art Smith (a playful all-day diner with cocktails and a kids menu) and Cask and Larder for Southern-inspired fare like chicken and waffles and pulled pork tacos.
A Brightline high-speed train station sits inside the airport complex next to Terminal C, connecting Miami and Orlando, and travelers do not need a flight to access it.
8. Harry Reid International Airport, Las Vegas (LAS) (26.5 million passengers)
Formerly McCarran International Airport, the Las Vegas gateway was renamed Harry Reid International Airport in December 2021, honoring the Nevada congressman who served from 1983 to 2017.
The airport has not historically wowed anyone, but a wave of impressive new lounges is changing that. Recent additions include American Express’s speakeasy-style Sidecar concept and a two-story, 5,390-square-foot Chase Sapphire Lounge with a champagne room.
In Terminal 1, Shake Shack near the B gates and Ruby’s Diner near the D gates are solid bets for a burger fix, while Jose Cuervo Tequileria near the C gates handles the margarita crowd. No matter which terminal you land in, slot machines are never far away.
9. Miami International Airport, MIA (26.4 million passengers)
Miami International Airport serves as a major gateway to the Caribbean, Latin America, and beyond, with a North Terminal (D gates), Central Terminal (E, F, and G gates), and South Terminal (H and J gates).
Accessibility is a genuine priority here. In June 2023, MIA became the first airport in Florida and only the second in the U.S. to receive accreditation through Airports Council International’s Accessibility Enhancement Accreditation program.
Services include a dry-run tour program for passengers with special needs, dedicated customs lanes, wheelchair charging stations, sunflower lanyards for travelers with hidden disabilities, multi-sensory rooms for neurodivergent passengers, and the Aira Airport Network for blind and low-vision travelers.
A MIA2Go app lets passengers order food from any terminal on their phone. Cuban food lovers should look for Café Versailles locations in the North and Central terminals, or Ku-Va near gate D19. Miami Beach brunch institution Icebox Cafe is also in the terminal, serving a full menu with a healthy lean.
10. San Francisco International Airport, SFO (26.2 million passengers)
About 13 miles south of downtown San Francisco, SFO is Northern California’s largest airport and a major gateway to Asia and the Pacific. United Airlines operates its primary West Coast hub here, and Alaska Airlines, Delta, and dozens of international carriers also fly through.
Lounge options are extensive: United runs multiple United Clubs and a Polaris Lounge, while others include the Delta Sky Club, Alaska Lounge, American Airlines Admirals Club, Air Canada Maple Leaf Lounge, and an Amex Centurion Lounge. British Airways, Cathay Pacific, Emirates, and Air France-KLM all maintain their own lounges as well, and Air India recently opened its first international signature Maharaja Lounge at SFO.
SFO is widely considered one of the best airports in the country for food. Local highlights include Boudin Bakery for sourdough bread bowls, Bun Mee for Vietnamese sandwiches, Proposition Chicken, Ritual Coffee, and Napa Farms Market showcasing Northern California products.
Full-service restaurants Lark Creek Grill and Mustards Bar and Grill offer a proper sit-down meal, and multiple wine bars celebrate the airport’s proximity to Napa and Sonoma.

One important note on the numbers: the Bureau of Transportation Statistics counts only passenger enplanements (those who boarded a plane), not arrivals.
Airports Council International counts both departures and arrivals, which is why passenger totals on global rankings look different.
