2025 has been an active year for Southeast Asia’s aviation sector, from fleet growth, new players in the market, and expanding MRO developments. We pulled together a snapshot of some of the notable movements across the region over the past year. Though not exhaustive, it reflects the momentum building in Southeast Asia’s aviation sector and why the region should not be overlooked globally.

Overall Statistics: Mixed Signals for Southeast Asia

Southeast Asia’s aviation market continues to show strong structural growth, but current indicators present a mixed picture.

On the demand side, the outlook remains positive. Boeing projects around 7% RPK growth and 6.6% fleet growth for Southeast Asia, placing the region among the fastest-growing globally. Southeast Asia is effectively tied with South Asia in traffic growth, supported by population expansion, a rising middle class, and the continued presence of low-cost carriers. At the same time, traffic remains highly concentrated, with the top five markets accounting for roughly 90% of total regional traffic. This concentration creates scale in key markets but also limits diversification across the region.

Capacity trends also reflect recovery and expansion. Total airline capacity in Southeast Asia increased about 5% year-on-year, reaching approximately 55 million seats in December 2025. The split between domestic and international capacity stands at roughly 43% and 57% respectively, with most international capacity directed toward other Asia-Pacific markets. This indicates that regional and near-regional demand continues to be the primary driver of growth.

However, connectivity has not fully recovered. Despite rising traffic and capacity, network connectivity remains below pre-COVID levels. A 2025 Deloitte report notes that 188 international airport pairs across Southeast Asia have yet to return. This suggests that while trunk routes and major markets have recovered, secondary and thinner routes are still lagging, affecting overall network depth and resilience.

Southeast Asia Airline Updates: New Entrants and Reshuffling

The Southeast Asian airline landscape in 2025 shows a mix of new entries, restarts, and exits, reflecting both confidence in market recovery and the realities of a competitive environment.

Several new or revived carriers are moving forward, particularly in Indonesia and Malaysia. Airlines such as FlyJaya and Sun Phu Quoc Airways commenced operations in 2025.  At the same time, not all ventures are moving in the same direction. The cessation of Jetstar Asia’s operations highlights the pressure on yields, cost structures, and network competitiveness, especially in highly contested markets like Singapore.

Overall, the pipeline of upcoming airlines, including projects like AirBorneo and Avion Express Philippines, suggests that investors and groups still see opportunity in Southeast Asia.

Beyond fleet and capacity movements, several structural and strategic developments are shaping Southeast Asia’s aviation landscape.

• MASwings divestment: Malaysia Aviation Group sold MASwings to the Sarawak state government in early 2025, pointing toward more regionally focused airline strategies, especially for secondary and rural connectivity.

• AirAsia group consolidation: Capital A consolidated its airline subsidiaries under a single AirAsia Group airline entity, aimed at simplification, cost control, and a clearer group structure.

• Rebranding moves: Cambodia Angkor Air rebranded to Air Cambodia as part of a broader repositioning and market identity refresh.

• Brunei’s recognition of CAAC certification for the COMAC C919 and C929 potentially lowers entry barriers for Chinese-built aircraft and supports prospective operators such as GallopAir.

• Lao Airlines confirmed a 49% stake acquisition by COMAC, indicating deeper OEM involvement in regional carriers.

• Indonesia consolidation watch: The proposed Pelita Air–Garuda Indonesia merger is under evaluation by Danantara, with no formal agreement or timeline yet. The outcome may shape future market structure and competition dynamics.

MROs in Southeast Asia – Selected Updates

Continued traffic growth and fleet expansion naturally translate into higher maintenance demand across the region. As utilization increases and fleets diversify, the need for line, base, and component support rises in parallel.

In response, both locally established MRO providers and international players are stepping up efforts to build or expand their footprint in Southeast Asia. The focus is not only on capacity, but also on capability, turnaround time, and proximity to operators’ core markets. Together, these trends point to a more competitive and capacity-conscious MRO landscape in the coming years.

Malaysia and Singapore account for the highest concentration of developments.

In Malaysia in particular, activity is largely concentrated in Peninsular Malaysia, and not far from its capital.

Southeast Asian Airlines at International Airshows

Southeast Asian carriers have shown selective participation in recent global airshows, with order activity varying by event.

• Dubai Airshow 2025: No new orders were placed by Southeast Asian airlines. Major headlines were driven instead by Gulf carriers, including Emirates’ order for 65 Boeing 777-9s and flydubai’s commitment for up to 150 A321neos.

• Paris Airshow 2025: Activity from the region was more visible, with Vietjet signing an MoU for 100 A321neos and options for 50 more, reinforcing its continued growth trajectory.

• Looking ahead — Singapore Airshow: The region’s own biannual airshow returns in February. In its 2024 edition, Southeast Asian carriers such as Cebu Pacific, Thai Airways, Vietjet, Royal Brunei, and Singapore Airlines announced a mix of aircraft orders and lease deals. Whether 2026 brings a similar wave of commitments will remain to be seen.

OEM Delivery & Orders

** For consistency, SEA is defined as the 11 ASEAN member states. Taiwan is excluded, although Boeing categorises it as part of Southeast Asia.

• Airbus met its revised 2025 delivery target of 790 aircraft, maintaining its delivery lead over 

• Boeing. This followed a reduction from its original 820-aircraft target due to fuselage-related production disruptions. Boeing, meanwhile, recorded a 72% year-on-year increase in deliveries. In October, Boeing and the FAA agreed, subject to regulatory approval, to increase 737 production from 38 to 42 aircraft per month. At the same time, Boeing pushed the expected 777-9 certification timeline to 2027, highlighting continued challenges on widebody programs.

• Largest SEA deal of 2025 came from Vietjet Air, which confirmed direct orders with Airbus for 20 A330neos and 100 A321neos across announcements in May and October. The airline cited network expansion and fleet modernisation as the main drivers, underlining the region’s continued preference for narrowbody growth complemented by selective widebody additions.

• Outside the Airbus–Boeing duopoly, COMAC has progressed more slowly, reportedly falling short of its own C919 delivery targets.

Regulatory Highlight - US Trade Policies

In 2025, Trump shook the industry by announcing a minimum global tariff of 10% (effective April 5th) and higher tariffs on specific countries and suspending the de minimis exemption for all countries

This decision is particularly a deviation from the status quo as the industry, particularly civil aviation, enjoys a low trade barrier and generally a duty-free zone as regulated by the 1979 ATCA

Exemptions & Agreements (per 14 Dec 2025)

With that being said, some trade agreements have been made with several countries to levy said tariff:

• UK, Malaysia, Cambodia, South Korea, Switzerland– exemptions for certain aircraft and aircraft parts products

• Japan, EU – 15% tariff ceiling and exemptions for certain products (including aircraft and parts)

• Brazil – 10% tariff, compared to 50% for most of its exports

Tariffs & Trade Deal – ASEAN countries (per 14 Dec 2025):

Aircraft Purchases in Relation to Trade Deal:

• Indonesia: Exploring 50 Boeing (777s) for Garuda

• Malaysia: Commit to purchase 30 Boeing aircraft as part of MAG renewal

• Thailand: Expressed commitment to purchase Boeing aircraft, but no exact numbers are confirmed

• Vietnam: Commit to purchase 50 Boeing aircrafts

• Cambodia: Pledged to buy 20 Boeing Max

Airworthiness Directives with 2025 Effective Dates

*Based on publicly available data (EASA Safety Publications Tool and FAA Dynamic Regulatory System). Cancelled and superseded ADs are excluded. Dates reflect effective dates.

Across FAA and EASA, the number of ADs with 2025 effective dates is higher than in the past three years for three aircraft families commonly operated in Southeast Asia.

Selected Notable ADs for 737NG and A320 Family

737NG

• Inlet cowl AD (following 2018 fan-blade-out events)

After separate fan-blade-out incidents in 2018 led to the separation of inlet and fan cowl parts, the FAA introduced requirements to inspect/replace (based on applicability) inlet cowl aft bulkhead fasteners, and for all, installation of crushable spacers.

• Landing gear hydraulic hose inspection (following a runway overrun)

Following the probe of a 2024 American Airlines runway overrun due to crossed hydraulic hoses, the FAA released an AD that requires general visual inspections of left and right MLG brake hydraulic hose installation, as well as testing of the anti-skid valve and transducer.

A320 family

• EASA Emergency AD – Flight control (ELAC)

EASA issued an Emergency Airworthiness Directive after an uncommanded pitch-down event linked to a potential fault in a flight-control computer (ELAC), on a JetBlue flight in October 2025. The directive had wide applicability, though many aircraft were able to return to service shortly after.

• On the horizon: A320 fuselage panel quality issue (proposed AD)

EASA has issued a proposed AD following a quality issue of one of Airbus’ suppliers that may have resulted in deviations from specified fuselage panel thickness on certain aircraft. If adopted, the AD would require a one-time general visual inspection and detailed thickness measurements, along with limitations on MMEL and SRM task usage.

While applicability and compliance effort vary by aircraft and operator, these developments point to increased maintenance actions and planning burden. They also highlight the importance of early planning and structured compliance management, rather than reactive execution.

Lingering Questions for Southeast Asia Aviation Landscape in 2026 and Beyond

The current momentum is clear, but several questions remain about how the region’s aviation landscape will evolve from here.

Capacity and maintenance pressure

More capacity means more potential income, but also increased fleet size and maintenance needs. But, with rising costs from maintenance and labor, higher parts prices, and a steady stream of new tasks, can airlines keep up?

Sustaining growth and new entrants

New airlines and expansions are emerging, but competition remains intense. How will these players compete, or even coexist, with established carriers?

Navigating geopolitics

From great-power rivalry and regional instability to supply-chain fragility and protectionism, pressures are mounting. How will Southeast Asian aviation balance domestic priorities with external geopolitical realities?
