Global air travel surged in 2024, with nearly 9.5 billion passengers recorded worldwide—up 9% from the previous year and now 3.8% above pre-pandemic (2019) levels. According to the latest rankings by Airports Council International (ACI) World, the aviation industry is entering a new phase of recovery and long-term growth, with Southeast Asia and the broader Asia-Pacific region playing a vital role in driving global momentum.

Top 10 Busiest Airports in the World by Passenger Traffic (2024):

Hartsfield–Jackson Atlanta International (ATL)– USA
Dubai International (DXB)– UAE
Dallas Fort Worth International (DFW)– USA
London Heathrow (LHR)– UK
Tokyo Haneda (HND)– Japan
Denver International (DEN)– USA
Istanbul Airport (IST)– Türkiye
Los Angeles International (LAX)– USA
New Delhi Indira Gandhi International (DEL)– India
Shanghai Pudong International (PVG)– China (up from 21st in 2023)

These 10 airports collectively handled a combined 855 million passengers, equivalent to 9% of global traffic, and exhibited strong recovery trends, with an 8.8% increase over 2023 and an 8.4% rise from 2019.

Asia-Pacific Momentum and Standout Performers

Shanghai Pudong (PVG)saw the most dramatic jump, climbing from 21st to 10th, fueled by China’s international reopening, upgraded facilities, and broader Asia-Pacific recovery.

Tokyo Haneda (HND)reclaims its place among the top 5 after Japan’s full reopening.

New Delhi (DEL) remains a strong contender, thanks to infrastructure development and airline expansion.

Across the Asia-Pacific region, tourism recovery, flexible visa policies, and regional connectivity have significantly boosted airport traffic.

Aircraft Movements – Back in the Sky

Aircraft movements globally reached nearly 100 million in 2024, a 4.3% increase from 2023, representing a 97.4% recovery from 2019 levels. The top three airports for aircraft movements were:

Hartsfield–Jackson Atlanta (ATL)– USA
Chicago O’Hare (ORD)– USA
Dallas Fort Worth (DFW)– USA

These airports collectively handled over 6.4 million flights, representing slight growth compared to pre-pandemic figures.

Thailand’s Aviation Growth and Future Outlook

Thailand’s aviation sector is experiencing significant growth, with Suvarnabhumi International Airport in Bangkok handling 62.2 million passengers in 2024—a 20% increase from 2023.

This growth highlights Thailand’s increasing significance in global air travel.

To accommodate increasing demand, Thailand is investing heavily in airport infrastructure:

Suvarnabhumi Airport is undergoing a £4 billion ‘masterplan’ expansion, including a new South Terminal and a fourth runway, aiming to handle up to 150 million passengers annually by 2033.

Phuket’s main airport is expanding to increase its capacity from 12.5 million to 18 million passengers per year by 2029.

A new Andaman International Airport is set to open in Phang Nga by 2032, designed to handle up to 22.5 million passengers annually.

Looking Forward: Long-Term Growth with New Challenges

In 2025, global air passenger traffic is projected to reach 9.9 billion, with a year-over-year growth rate of 4.8%. However, the pace of expansion is expected to moderate, moving from recovery-driven growth to long-term structural trends.

Emerging markets, particularly in Southeast Asia, are expected to continue growing rapidly, driven by infrastructure investment and the rise of the middle class, which is leading to increased travel. Conversely, mature markets face capacity challenges, production delays, and economic headwinds.

Industry Leadership Insight

“The resilience of the world’s busiest airports shines amid global challenges,” said Justin Erbacci, Director General of ACI World. “These hubs are not just transport nodes—they are vital arteries of global trade, commerce, and connectivity. As we enter a new phase, infrastructure investment and operational excellence will define success.”
