The United States is home to some of the busiest airports in the world. In fact, a recent report released by Airports Council International (ACI) World revealed that eight of the world’s 20 busiest airports in 2023 are located in the US.

There is a strong rebound in post-pandemic travel

Each year, ACI releases the Annual World Airport Traffic Dataset, created using airport traffic data collected through its global network of airport operator members, investors, and aviation stakeholders. The dataset encompasses more than 2,700 airports in over 185 countries and territories.

The 2024 report, which covers statistics from 2023, found that total global traffic in 2023 was close to 8.7 billion – representing a 30.5% rise over 2022 and a recovery of 94.2% from pre-pandemic (2019) results. This positively signifies a strong and continued resurgence in international traffic.

Worldwide passenger levels are growing quicker than expected, despite a slower recovery in Asia-Pacific.

ACI World Director General and CEO Luis Felipe de Oliveira said:

“The dataset findings indicate that the demand for air travel is as strong as ever. International passenger traffic has now almost fully recovered from the pandemic, and the regional disparities are gone.”

US airports claim eight spots on the list

The top 20 busiest airports in the world served 1.41 billion passengers in 2023, accounting for 16% of global passenger movements.

Interestingly, the report found that almost all of these airports have significant domestic passenger shares – between 70% and 95% – illustrating the sheer volume of domestic travel in the US.

ATL remains the busiest airport in the world

ATL is consistently ranked as the busiest airport in the world by passenger numbers – and in 2023, it maintained its grip on the throne, serving 104,653,451 passengers. What’s even more impressive is that it handled close to 18 million more passenger movements than the second-busiest airport in the world, Dubai International Airport (DXB).

Nonetheless, all eight airports remained among the world’s top 20 busiest airports in both 2022 and 2023 – with six maintaining a place on the list from 2019. Significantly, MCO and LAS were not on the list prior to the pandemic, having increased their passenger volumes post-COVID.

Half the eight airports handled more passengers post-pandemic

Although all of the 20 busiest airports have seen an improvement in passenger numbers compared to 2022, as mentioned earlier, passenger traffic has not yet recovered to pre-COVID levels. In 2023, ATL, LAX, ORD, and JFK handled passenger volumes that were between 0.1% and 14.8% lower than in 2019.

Why Is Denver Airport So Big?

Denver Airport is two times larger than its closest US counterpart.

The most significant is DEN, which saw a 12.8% improvement in passenger volumes against pre-COVID figures. Famous for its distinctive tent-like terminal architecture, the airport’s innovative design and strategic location make it a significant hub for flights across the US and beyond.

The US is the only country with more than one airport on the list

These eight US airports are not only some of the busiest in the world but also serve as critical hubs for domestic and international travel. It’s also worth highlighting that, in terms of cargo movements, seven US airports made it into ACI’s list for air cargo movements – accounting for nearly half of the world’s 20 busiest cargo hubs in 2023. They are: MEM, ANC, SDF, MIA, LAX, ORD, and CVG.
