These days, it’s difficult to imagine a world without air travel. According to the annual report by the Airports International Council, nearly 7 billion travelers took to the skies in 2022 alone — an increase of 53.5% from the pandemic lockdowns of the previous year. And while there are more than 41,000 airports dotting the globe, some handle far more of that traffic than the rest. Below, take a look at the world’s 10 busiest airports by total passengers enplaned and deplaned in 2022.

Handling almost 57.5 million passengers annually, Paris Charles de Gaulle (also known as Roissy Airport or Paris CDG) is the principal hub for French flag carrier Air France. The airport is named after French army officer and statesman Charles de Gaulle, who was the architect of France’s Fifth Republic in the 1950s. The airport’s three main terminals accommodate flights to 119 countries around the globe, just behind Istanbul Airport in terms of network breadth. Inside Terminal 2, the Espace Musées features works of art loaned from renowned Parisian cultural institutions such as the Rodin Museum. To fend off boredom on a long layover, budding musicians can also play the free-to-use pianos in all three terminals.

Located in southwest Delhi, one of the world’s most populous metro areas, Indira Gandhi International Airport is currently the busiest airport in India. Latest figures account for just under 59.5 million passengers in 2022. Open since 1962, the airport — named after former Prime Minister Indira Gandhi — is served by 80 airlines and is the main hub of India’s flag carrier, Air India. Throughout the three terminals, passengers can access over 75 retail outlets and 65 food and drink establishments.

Passengers traveling through Heathrow can find around 130 retail shops to pass the time, along with more than 30 bars, cafés, and restaurants. The airport is named after the ancient hamlet called Heath Row, where the airport was built following World War II.

Situated on the European side of Istanbul, Istanbul Airport has been Turkey’s main international air traffic gateway since it opened in 2018. It replaced Atatürk Airport, which was unable to expand due to its proximity to city developments and the Sea of Marmara. In 2022, the new Istanbul Airport connected around 64.3 million passengers to and from nearly 300 destinations in Asia, Africa, the Americas, and Europe — more destinations than any other airport in the world. In addition to a wide range of shops and restaurants, the airport has dedicated and complimentary Rest and Entertainment areas. Among these is the Youth Lounge, a space for travelers aged 15 to 30 with free Wi-Fi, comics, and video and board games.

6. Los Angeles International Airport (LAX) – California

Famed for the 135-foot-tall Space Age-inspired Theme Building at the center of its terminal complex, Los Angeles International Airport is the fifth-busiest airport in the U.S. Just over 65.9 million passengers used the airport’s nine terminals and 150 gates in 2022. LAX’s Tom Bradley International Terminal, named after the city’s longest-serving and first Black mayor, serves over 40 foreign carriers and underwent a major expansion in 2021, with the addition of a new 15-gate concourse. With a mission to celebrate the talents of South Californian artists, the LAX Art Program puts on 20 exhibitions a year in the departure and arrival areas.

Built on the site of a former Douglas aircraft assembly plant, Chicago O’Hare International Airport became one of America’s main getaways to the world after opening in 1945. Named after naval aviator Lieutenant Commander Edward H. “Butch” O’Hare, the airport is a major hub for both American Airlines and United Airlines. Today, O’Hare handles approximately 68.3 million passengers annually over its four terminals, which boast nearly 200 aircraft gates.

Framed by the Rocky Mountains, Denver International Airport is both one of the busiest — serving 69.3 million passengers in 2022 — and most architecturally impressive airports in the world. DIA (as locals call it) serves as a hub and focus city for United Airlines, Southwest Airlines, and Frontier Airlines — with around 1,700 flight movements per day. The exterior of the main Jeppesen Terminal is notable for its fabric-covered tents, which symbolize the Rockies, prairie wagons, and the teepee tents of Native Americans. Boasting a 9,000-panel solar farm that generates 3.5 million kilowatts of electricity annually, the airport opened in 1995 and was designed with sustainability in mind. Throughout the terminal, passengers can also embrace Colorado culture through the DEN Arts displays.
