The Biggest and Busiest Airports in the World in 2020

Have you ever been running late to catch a flight and struggled with the never-ending hallways and escalators you need to pass to reach your gate?

The biggest airports in the world make it feel like you’re walking through an entire city when you’re inside.

In 2020, they’re expecting over four billion passengers to travel by air. Now the biggest airports are also becoming the busiest airports in the world.

Since the airports are getting busier, they’re building bigger airports to accommodate all the passengers.

In September 2019, the world’s largest airport (based on area size) opened in Beijing, China. The Beijing Daxing International Airport will be able to handle over 100 million passengers per year.

Good thing for the passengers, they won’t have to worry about walking a marathon to get to their gate.

Architects are taking these considerations into their designs and balancing both size and convenience.

The architect who designed the new Beijing airport, Zaha Hadid, made a futuristic design in a starfish shape, making it easy for passengers to reach their gate in less than 8 minutes.

It will be interesting to see how airport design evolves in the years to come!

In the meantime, let’s take a look at all of the “superairports” of the world, both in terms of area size and the number of passengers they serve.

This airport is Beijing’s second international one in the city and it’s expected to also become the world’s busiest, with 100 million passengers passing through by 2040.

Nicknamed the “starfish”, after architect Zaha Hadid’s futuristic design, the airport was built for both convenience and eco-friendliness.

The starfish design makes it easy for passengers to travel from security to their gate in under eight minutes.

Its solar panels, waste heat recovery, and water management systems limits the environmental impact that such a big airport can make to the ecosystems in the area.
