Airports and the air connectivity they facilitate supported 23.3 million jobs and contributed $244 billion to the economies of ASEAN member states in 2025, according to a new study by Airports Council International Asia-Pacific & Middle East (ACI APAC & MID).
The report, titled Strengthening the ASEAN Single Aviation Market (ASAM) for Greater Connectivity within and beyond ASEAN, provides a comprehensive assessment of the economic contribution of airports across the region. It examines aviation’s role in supporting trade, tourism, investment and employment, while identifying infrastructure, policy and connectivity challenges that could constrain the development of the ASEAN Single Aviation Market.
Airport-related activity alone generated $55 billion in GDP and supported 1.6 million jobs across ASEAN in 2025. This figure includes direct airport operations, supply-chain activity and household spending linked to the sector.
The aviation ecosystem also generated an estimated $36 billion in government tax revenues, including $8 billion directly from airport activity and another $28 billion through its wider economic impact across the 11 ASEAN states.
The study highlights the substantial expansion of regional air connectivity since ASAM was introduced. Direct connectivity between ASEAN countries increased by 358% from 2004 to 2025, with the resulting expansion associated with approximately $50.6 billion in GDP and six million jobs.
Almost every ASEAN member state recorded at least a doubling of scheduled seat capacity over the same period. Much of the intra-ASEAN expansion occurred between 2010 and 2015, coinciding with the signing of several protocols linked to ASAM.
Low-cost carriers have also become increasingly important to regional connectivity. They accounted for 51% of intra-ASEAN seats in 2025, compared with 29% in 2008, helping make air travel more accessible across the region.
Vietnam, Indonesia and Malaysia recorded the largest employment impacts from airport-related activity, with approximately 368,000, 335,000 and 282,000 jobs respectively. Singapore, Malaysia and Thailand recorded the largest GDP impacts, at around $22 billion, $11 billion and $7.7 billion.
Tourism was another major beneficiary of expanded connectivity. An estimated 84.8 million international tourists arrived in ASEAN by air in 2025, generating approximately $127 billion in tourism spending, equivalent to about two-thirds of the region’s total international tourism expenditure.
ASEAN airports handled more than 700 million passengers and nearly nine million tonnes of cargo during the year.
The report also identifies significant additional economic gains that could result from full implementation of ASAM. Under an unconstrained scenario, the policy could generate nearly six million additional intra-ASEAN passengers, representing an 11.6% increase over 2025 traffic.
That growth could support an additional 15,000 aviation-sector jobs and generate $600 million in GDP, while tourism, trade, investment and other wider economic effects could add another 434,000 jobs and $3.7 billion in GDP. Combined, the potential benefit could approach 450,000 additional jobs and $4.3 billion in GDP.
Stefano Baronci, Director General of ACI Asia-Pacific & Middle East, said ASAM had delivered significant progress but that further measures were needed to unlock its full potential. He called for greater market access and traffic rights, including expanded connectivity to secondary cities so that more local economies can benefit from increased aviation activity.
The study cautions that liberalisation alone will not be enough to achieve the projected gains. Airport and airspace capacity, infrastructure investment and supportive regulatory frameworks will also be necessary as passenger demand continues to rise.
Baronci said limited airport infrastructure development remains a key constraint on liberalisation in Southeast Asia, restricting airlines’ ability to take full advantage of opportunities created by ASAM.
ACI Asia-Pacific & Middle East estimates that ASEAN airports will require around $108 billion in investment by 2036 to accommodate expected traffic growth. A further $233 billion could be needed between 2037 and 2056 as regional passenger traffic is projected to reach 2.9 billion.
That would put the estimated 30-year airport investment requirement at approximately $341 billion.
Baronci said meeting future demand would require airports to mobilise substantial capital to expand capacity, modernise infrastructure and remain competitive. He also urged ASEAN members to accelerate the implementation of existing air services agreements and address remaining capacity, regulatory and operational barriers to support sustainable aviation growth.
