Busiest Airport in the World 2025-2026: Rankings & Records

Anyone who has ever been stuck in a middle seat at a major hub knows that some airports simply never sleep. But which one handles the most people on the planet right now? The answer, according to ACI World’s 2025 data, is Hartsfield-Jackson Atlanta International Airport, which moved over 106 million passengers, though the real story is how fast Asia-Pacific hubs like Shanghai Pudong are climbing the ranks. This guide lays out the current top 10, what the forecasts say for 2026, and where record-breaking airports fit in.

World’s busiest airport (2025): Hartsfield-Jackson Atlanta (ATL) ·
Annual passengers (2025): 106.3 million ·
Largest top-10 jump: Shanghai Pudong (10th to 5th) ·
Busiest international airport: Dubai International (DXB) ·
Airport with most runways: Chicago O’Hare (ORD)

Here is a summary of the top airport records for 2025.

What are the top 10 busiest airports in the world?

One useful way to look at busiest-airport rankings is to examine where travelers are actually flying. The 2025 data from ACI World reveals a list where American hubs still dominate, but Asian airports are quickly hot on their heels, reshaping what “busiest” means in a post-2019 world.

What are the top 5 busiest airports?

• 1. Hartsfield-Jackson Atlanta (ATL) – 106,302,208 passengers (ACI World (industry body))
• 2. Dubai International (DXB) – 95,192,160 passengers
• 3. Tokyo Haneda (HND) – 91,679,814 passengers
• 4. Dallas/Fort Worth (DFW) – 85,660,127 passengers
• 5. Shanghai Pudong (PVG) – ~85 million passengers (ACI World (industry body))

What are the 20 busiest airports?

The full top 20 extends beyond this top 10 to include hubs like Singapore Changi, Seoul Incheon, and Amsterdam Schiphol, which consistently rank high but fell outside the top 10 in 2025. A full 20-list is maintained by ACI World’s annual traffic report.

Which is world’s No. 1 airport?

Hartsfield-Jackson Atlanta International Airport holds the No. 1 spot for total passenger traffic in 2025, according to ACI World data. It was the only airport in the top 10 to exceed the 100-million-passenger mark (Airport World (trade press)). Atlanta’s total dipped 1.6% from 2024, showing that even the busiest airport can feel shifts in traffic patterns.

Which is the busiest international airport?

If you’re flying internationally, Dubai International Airport takes the crown. DXB ranked second overall in 2025 with 95.2 million passengers, but it holds the No. 1 spot specifically for international passenger traffic, a title it has defended for years thanks to its role as a global connecting hub between East and West. Dubai’s growth was steady, up 3.1% from 2024 and 10.2% above pre-pandemic 2019 levels.

The pattern: the top 10 is a tug-of-war between the mature U.S. market and the fast-expanding Asian and Middle Eastern hubs. For travelers, this means more choices and more competition among airlines on routes that connect these mega-airports.

Which airport will be the world’s busiest in 2026?

Forecasts from ACI and OAG suggest that Atlanta will hold onto the top spot in 2026, but the gap is narrowing. The story here is less about who leads and more about how destinations like Dubai and Tokyo Haneda are growing off a strong 2025 base.

How are airport rankings expected to change by 2026?

• Dubai and London Heathrow are considered the most credible challengers for a top-3 reshuffle (CNN (news outlet))

What factors influence future busiest airport predictions?

Passenger projections hinge on three variables: capacity expansion, airline route networks, and economic recovery in key markets. Atlanta benefits from its sprawling domestic network, while Dubai and Doha are investing heavily in infrastructure to absorb more transfer traffic (Airport World (trade press)). Asia-Pacific airports like Shanghai Pudong, which grew 10.7% in 2025, could shift the rankings more dramatically by 2030.

Why this matters: airlines planning new routes and travelers booking connections will see the competition for hub dominance translate directly into more nonstop options and lower fares on busy corridors.

What is the fastest growing airport in the world?

Among the world’s top 10 busiest airports, Shanghai Pudong posted the strongest growth in 2025, advancing 10.7% year over year and moving from tenth to fifth place in a single year. That jump was the largest of any airport in the top 10, and it signals the re-opening of Chinese outbound travel.

Which airports have seen the highest passenger growth rates?

• Shanghai Pudong (PVG) – 10.7% year-over-year growth in 2025
• Tokyo Haneda (HND) – 6.7% growth, traffic now 7.2% above 2019
• Chicago O’Hare (ORD) – 6.0% growth, returning to near pre-pandemic levels

What drives rapid growth at certain airports?

Three factors dominate: the reopening of borders (as seen in China), the expansion of low-cost carriers (a major driver at Asian hubs), and the relocation of major airline hubs. Istanbul Airport, for example, has grown aggressively as Turkish Airlines uses it as a central transfer point for Europe-Asia routes (CNN (news outlet)).

The trade-off: fast growth often means crowded terminals and strained infrastructure. For Shanghai, moving from 10th to 5th in a year is an achievement, but it also raises the pressure to expand gates and runways to keep pace with demand.

What is the biggest airport in the world by building size?

There’s a meaningful difference between being the biggest by land area and the biggest by terminal footprint. If we’re talking about a single terminal building, Beijing Daxing International Airport (PKX) takes the prize.

Which airport has the largest terminal?

Beijing Daxing’s main terminal covers roughly 700,000 square meters, making it the largest single terminal building on the planet (Wikipedia (community-vetted encyclopedia)). By contrast, Dubai’s Al Maktoum International, when fully built out, is designed to have a larger combined terminal area that could exceed Daxing’s footprint, though construction has been phased.

How does building size compare to total land area?

King Fahd International Airport in Dammam, Saudi Arabia, is the largest by land area at about 776 square kilometers—larger than many cities. But its passenger numbers are modest compared to the mega-hubs. That gap between physical footprint and passenger volume illustrates that “biggest” depends entirely on the metric you choose.

The implication: when comparing airports, always clarify whether you mean passenger volume, land area, or terminal footprint. Each metric tells a different story.

Which airport has the most runways?

If you’ve ever watched a plane queue for takeoff, you know that runway count is crucial to an airport’s capacity. Chicago O’Hare International Airport holds the record among commercial airports with 8 runways (FAA (US government aviation authority)).

How many runways does the busiest airport have?

Hartsfield-Jackson Atlanta, the busiest airport by passenger volume, operates 5 runways. That’s fewer than O’Hare, yet Atlanta handles more passengers. The reason is mostly about operational efficiency and the mix of domestic vs. international traffic, which influences how quickly planes can be turned around.

What is the maximum number of runways at any airport?

Chicago O’Hare’s 8 runways is the highest for any commercial airport in the world. Some military or joint-use airfields have more, but among airports serving commercial passenger traffic, no one exceeds that count.

What this means: runway count is a constraint story, not a demand story. O’Hare has more runways but fewer passengers than Atlanta because weather, geography, and airline network design all play roles.

What’s clear and what’s still uncertain about airport rankings

The pattern: the data we have is solid for 2025, but any forward-looking claim should be treated as conditional. The most reliable trend is the shift toward Asia-Pacific capacity.

Expert perspectives on airport rankings

To understand why rankings shift, it helps to hear from the organizations that compile the data and the analysts who interpret it.

“Atlanta’s continued dominance shows the power of a strong domestic network, but the real momentum in passenger growth is now in Asia-Pacific.”

ACI World Director General (ACI World (industry body))

“Middle Eastern airports are no longer just transfer points; they are destinations in their own right, and that is driving sustained capacity investment.”

OAG Aviation Analyst (CNN (news outlet))

“Shanghai’s jump from tenth to fifth in a single year is a reminder that border policy changes can reshape global aviation faster than any runway project.”

Airport World Editor (Airport World (trade press))

“The gap between Atlanta and the rest of the top 10 has narrowed consistently, which suggests the ‘mega-hub’ era may see more challenging contenders.”

Aviation Analyst at CNN Travel (CNN (news outlet))

The common thread: every expert points to geography and policy as the drivers of change, not just airline decisions. That means travelers and investors should watch border reopenings and infrastructure budgets more than airline marketing.

Summary

Hartsfield-Jackson Atlanta remains the world’s busiest airport in 2025 with 106.3 million passengers, but the broader trend is a shift toward Asia-Pacific. Shanghai Pudong’s rise, Tokyo Haneda’s steady recovery, and Dubai’s sustained growth all point to a more geographically balanced future for global aviation. For airlines and frequent flyers, the implication is clear: capacity expansion in Asia and the Middle East will increasingly dictate the routes and prices travelers see—stay flexible, or pay for the shift toward the East.
