10 Largest Airports in the World (2026) – Bigger Than Some Cities

Believe it or not, the largest airports in the world cover more land than many cities. King Fahd International in Saudi Arabia alone spreads over about 780 square kilometres – mostly desert held in reserve for future growth – and several others are bigger than 100 km². Here are the 10 largest airports in the world by land area, with the latest figures for 2026.

Size and traffic are two very different things: the biggest airports are rarely the busiest. The world’s busiest airport, Hartsfield–Jackson Atlanta International, handled about 106 million passengers in 2025 on a fraction of the land of the giants below.

The 10 largest airports in the world (2026)

1. King Fahd International (DMM) – Dammam, Saudi Arabia

With about 780 km², King Fahd International is by far the largest airport in the world – more than five times the size of the runner-up. Only a small part of that land is used by the terminals and runways; the rest is a reserve set aside for future expansion.

The airport opened to commercial traffic in 1999 and serves Saudi Arabia’s Eastern Province, including Dammam, Khobar and Dhahran. It handled around 11 million passengers in 2023, and also has a separate Royal Terminal for the Saudi royal family and official guests.

2. Denver International (DEN) – Colorado, USA

Denver International covers 135.7 km² (33,531 acres), making it the largest airport in the United States and the second largest in the world. It opened on 28 February 1995.

Its six runways include a 16,000-foot runway – the longest public-use runway in North America – and its peaked white roof, designed to echo the snow-capped Rocky Mountains, is one of the most recognisable in aviation. Denver handled about 82 million passengers in 2025, ranking among the busiest airports in the world.

3. King Abdulaziz International (JED) – Jeddah, Saudi Arabia

King Abdulaziz International spreads over about 112 km². As the main gateway for pilgrims travelling to Mecca, it is famous for its Hajj Terminal, whose huge tent-like roof shelters travellers during the pilgrimage season.

A new main terminal (Terminal 1) opened in 2019, and the airport handled more than 50 million passengers in 2023.

4. Kuala Lumpur International (KUL) – Malaysia

Kuala Lumpur International covers around 100 km² and opened in 1998. It is Malaysia’s main hub and has two terminals: the main terminal with its satellite building – which has a small rainforest garden at its centre – and klia2, opened in 2014 for low-cost airlines.

The airport handled about 63 million passengers in 2025.

5. Istanbul Airport (IST) – Turkey

Istanbul Airport covers about 76 km². It opened in 2018 and took over all of the city’s scheduled passenger flights from Atatürk Airport in 2019.

It is the home of Turkish Airlines, which flies to more countries than any other airline, and handled about 84.5 million passengers in 2025 – one of the busiest airports in Europe. When all of its planned phases are complete, it is designed to handle up to 200 million passengers a year.

6. Dallas/Fort Worth International (DFW) – Texas, USA

Dallas/Fort Worth covers about 69.5 km² (17,183 acres) – larger than the island of Manhattan. It opened on 13 January 1974 and is the largest hub of American Airlines.

DFW has five terminals linked by the Skylink automated train and seven runways, and it ranks among the ten busiest airports in the world by passengers.

7. Orlando International (MCO) – Florida, USA

Orlando International covers about 47 km² (11,605 acres). As the gateway to Walt Disney World and Orlando’s theme parks, it is one of the busiest airports in the United States, with about 58 million passengers in 2025.

Its newest building, Terminal C, opened in 2022.

8. Washington Dulles International (IAD) – Virginia, USA

Washington Dulles covers about 45.3 km² (11,184 acres). It opened in 1962 and is named after John Foster Dulles, US Secretary of State under President Eisenhower.

Its main terminal, designed by architect Eero Saarinen with a sweeping curved roof, is considered a landmark of modern architecture. Dulles is a major hub for United Airlines.

9. Beijing Daxing International (PKX) – China

Beijing Daxing covers roughly 45 km² (published figures vary). It opened in September 2019, and its starfish-shaped terminal, designed by Zaha Hadid Architects, is one of the largest single airport terminal buildings in the world.

Daxing handled about 54 million passengers in 2025.

10. Kansas City International (MCI) – Missouri, USA

Kansas City International covers about 43.2 km² (10,680 acres). A brand-new single terminal opened in February 2023, replacing the airport’s three older terminals.

It handled about 12 million passengers in 2024 – a reminder that the biggest airports by area are not necessarily the busiest.

Final thoughts

Several of the world’s biggest airports were built on huge plots of land to leave room for decades of growth, which is why the desert giants of Saudi Arabia top the list.
