Cargo Operations in Southeast Asia: Network and Fleet Strategies

The earlier articles in this series have focused on passenger operations: how airlines structure their networks (Hub-and-Spoke vs Point-to-Point), how they finance their fleets (Aircraft Lease Structures and Wet Lease/ACMI), and how they choose between charter and scheduled service. This article turns to cargo operations, which sit alongside passenger flying as a parallel and increasingly important commercial activity. In Asia-Pacific specifically, the cargo business has grown rapidly through 2025 and into 2026, driven by e-commerce volumes, semiconductor and AI-related supply chains, and the structural shift of global trade flows away from the US-Asia corridor toward intra-Asia and Asia-Europe routes.

For network planners, fleet planners, and finance teams at Asian regional carriers, cargo is no longer a sideline. It is a strategic question with implications for fleet selection, hub investment, alliance strategy, and the operator’s overall positioning in the regional aviation market. This article walks through the framework.

1. The global cargo picture in 2025-2026

The headline numbers from IATA’s December 2025 and January 2026 releases tell a clear story. Global air cargo demand grew approximately 3.1% in 2025, with Asia-Pacific carriers leading at 8.4% year-on-year demand growth. December 2025 was especially strong: global demand rose 4.3% year-on-year, with Asia-Pacific carriers surging 9.4% (international Asia-Pacific traffic rose 10.7% in the same month). The region accounted for 34.3% of global cargo tonne kilometres by region of carrier, the largest single share.

The drivers behind these numbers shifted meaningfully through 2025. The US tariff increases starting in April 2025 and the removal of the de minimis exemption (which had previously allowed parcels under USD 800 to enter the US duty-free) sharply reduced the Asia-North America cargo corridor, which contracted 2.6% over the full year. In contrast, the Europe-Asia corridor expanded 14.7%, becoming the principal growth engine of the global air cargo market. Intra-Asia traffic also strengthened.

For 2026, IATA forecasts moderating growth, projecting 2.4% global demand expansion against a target of 71.6 million tonnes carried. Asia-Pacific is expected to remain the primary source of incremental demand, with semiconductor and AI-related supply chains, electric vehicle component flows, and continued e-commerce expansion as the major underlying drivers.

The capacity side of the equation is more constrained. While belly cargo capacity (cargo carried in the lower deck of passenger aircraft) expanded strongly in 2025 as passenger networks recovered and grew, dedicated freighter capacity has been limited by ongoing aircraft delivery delays, an ageing global freighter fleet, and the relatively scarce supply of suitable aircraft for passenger-to-freighter (P2F) conversions. IATA reports global available freight tonne kilometres rising 4.5% year-on-year against demand rising at higher rates, with cargo load factor holding around 47.1%. Capacity discipline is expected to persist through 2026.

2. The Southeast Asian cargo hub landscape

Three primary cargo hubs dominate the ASEAN region, each with distinct positioning and strategy.

Singapore Changi handled approximately 2.08 million tonnes of airfreight in 2025, a 4.5% year-on-year increase, marking one of its strongest cargo years on record. Q1 2026 throughput continued the growth, reaching 517,000 tonnes (a 7.6% year-on-year increase). The major drivers are exports, imports, and transhipment flows, with semiconductors, AI-related supply chains, electric vehicles, and cleantech as the highest-value contributors. China remains Changi’s largest air cargo market, followed by the United States, Australia, Hong Kong, and India.

Changi’s strategic positioning is reinforced by an ambitious capacity expansion. The airport is investing to lift cargo handling capacity from 3 million tonnes per year to 5.4 million tonnes by the mid-2030s, through development of Terminal 5, the Changi East Industrial Zone, and a major expansion of the Airport Logistics Park of Singapore (ALPS 2). New freighter services launched in 2025 include JD Airlines’ thrice-weekly Shenzhen-Singapore service, Turkish Cargo’s restart of Istanbul-Ho Chi Minh City-Singapore freighter operations, and Qantas Freight’s twice-weekly Sydney-Shanghai-Singapore service. All four global express integrators (DHL, FedEx, SF Express, and UPS) operate at Changi, with FedEx using the airport as its South Pacific Regional Hub.

Kuala Lumpur International Airport (KLIA) hosts MASkargo (formally MAB Kargo, the cargo division of Malaysia Aviation Group) at its Advanced Cargo Centre, a 108-acre facility with 92,900 square metres of processing area and an annual handling capacity of 1 million tonnes (expandable to 3 million). MASkargo’s freighter fleet consists of three Airbus A330-200F aircraft (each with approximately 61 tonnes capacity), supplemented by belly-cargo capacity on the Malaysia Airlines passenger fleet. The cargo network spans Asia, Australia, and Europe, with current freighter services to Kuching, Kota Kinabalu, Labuan, Penang, Bangkok, Chennai, Mumbai, Shanghai, Hong Kong, Manila, Hanoi, and Sydney, plus Amsterdam via Doha. KLIA also hosts the Free Commercial Zone, a tax-free area of over 1,000 acres designed for high-value, high-volume air freight.

In late 2024, MASkargo issued a tender seeking a Boeing 737-800 freighter operating partner to expand its regional Asia network. The proposed routes targeted shorter-haul connections between Kuala Lumpur and regional points where the A330F is uneconomically large but where consistent demand justifies dedicated freighter capacity. The strategy reflects a broader pattern across the region: combining widebody freighter capacity for trunk routes with narrowbody freighters or wet-leased capacity for regional feeders.

Bangkok Suvarnabhumi hosts Thai Airways International’s THAI Cargo division, operating from a 90,000 square metre warehouse with annual capacity of approximately 1.2 million tonnes. THAI Cargo’s model relies primarily on belly capacity from Thai Airways’ widebody passenger fleet (Airbus A350s, Boeing 777s, and Boeing 787s), with the airport’s general cargo activity supplemented by foreign freighter operators serving Thailand’s electronics and perishables export flows. Suvarnabhumi serves as the operating base of 113 airlines (2025), the most of any airport globally, providing diverse belly-cargo capacity across multiple destinations.

Jakarta Soekarno-Hatta (CGK) is the primary hub of Garuda Indonesia and its subsidiary Garuda Cargo. Unlike SIN, KLIA, and BKK, CGK’s cargo profile is more weighted toward serving the very large Indonesian domestic market, with international cargo flows depending heavily on belly capacity from a wide range of passenger carriers operating into Indonesia. Cargo movements between Shanghai and Jakarta, for example, are carried by Garuda Indonesia, China Eastern, VietJet Air, EVA Air, Singapore Airlines, China Airlines, Vietnam Airlines, Malaysia Airlines, Philippine Airlines, Thai Airways, Korean Air, and others, reflecting the connectivity of CGK to multiple ASEAN, Northeast Asian, and global hubs.

For comparison context, Hong Kong International Airport (HKIA), while technically not within ASEAN, remains a critical reference point for any Southeast Asian cargo discussion. HKIA handled approximately 5.07 million tonnes of cargo in 2025, retaining its position as the world’s busiest cargo airport for the 14th time since 2010. The competitive dynamic between Hong Kong and the ASEAN hubs continues to evolve, particularly as US tariff measures reshape the East Asia trade map and as China-based operators increasingly look at southbound flows through ASEAN gateways.

3. Cargo airlines and freighter fleets in the region

The dedicated cargo airline landscape in Southeast Asia is concentrated, with a small number of operators handling the bulk of the dedicated freighter capacity, supplemented by integrator operations and a wider belly-cargo network.

Singapore Airlines Cargo (SIA Cargo) operates as a division of Singapore Airlines rather than a separate subsidiary. The unit relies primarily on belly capacity from the parent airline’s widebody passenger fleet, but the 2022 partnership with DHL Express adds a dedicated freighter dimension: five DHL-owned Boeing 777Fs operate in dual DHL-SIA livery, flown by SIA pilots, primarily serving DHL Express’ South Asia Hub at Changi with routes to the United States via points in North Asia. This hybrid structure (lessor-owned aircraft, lessee-crewed operations, dedicated to express integrator service) reflects how complex modern cargo arrangements can be.

Cathay Cargo, the cargo division of Cathay Pacific, is the dominant freighter operator in Greater China and the largest contributor to HKIA’s cargo throughput. The fleet consists of six Boeing 747-400ERF freighters and 14 Boeing 747-8F freighters as of year-end 2025, with eight Airbus A350F freighters on order (after Cathay exercised purchase rights for two additional aircraft, bringing the total commitment from six to eight). Cathay Cargo offered over 100 return freighter flights per week to more than 40 destinations from Hong Kong in 2025. The A350F deliveries beginning later in the decade will gradually modernise and diversify the fleet, while reducing fuel burn and emissions on the long-haul cargo network.

Cathay Group’s Air Hong Kong, which operates express cargo services primarily for DHL Express, completed its seven-year re-fleeting programme in June 2025, transitioning to an all-A330F fleet of 14 aircraft (10 A330-300P2F passenger-to-freighter conversions and 4 A330-200F factory-built freighters). Air Hong Kong was the world’s first carrier to operate the A330P2F.

MASkargo (covered above) provides the dedicated Malaysian freighter capacity, with the A330-200F fleet serving the Asia-Europe trunk and the proposed 737-800F partnership intended to extend regional coverage.

THAI Cargo and Garuda Cargo operate primarily through belly capacity rather than dedicated freighters, with their parent airlines’ widebody passenger fleets providing the lift. This is a different model from the SIA-DHL or MASkargo configurations, and it carries different commercial implications: belly cargo capacity is highly variable with passenger schedule changes, but the marginal cost per tonne is very low because the fixed costs are absorbed by passenger operations.

Outside the flag-carrier model, several Southeast Asian operators target specific cargo niches. Cebu Pacific in the Philippines operates a small dedicated freighter fleet (ATR 72 freighter aircraft) for inter-island parcel service, supplementing its primary belly-cargo operation. Cardig Air in Indonesia operates Boeing 737-400 and 737-300 freighters for domestic and intra-Asia cargo, often under ACMI contracts to integrators. Sky Aviation Cargo Vietnam and various other smaller carriers occupy specific market niches.

The major global integrators (DHL, FedEx, UPS, SF Express, ANA Cargo) all operate substantial networks through ASEAN hubs, often through wholly-owned freighter operations or through dedicated wet-lease arrangements with local operators. The integrator share of total ASEAN cargo volumes continues to grow alongside the express parcel and e-commerce flows.

4. The e-commerce driver

E-commerce has reshaped global air cargo flows over the past five years, and the Southeast Asian segment of that shift is among the most significant. Three platform categories drive the bulk of the change:

Chinese cross-border platforms (Shein, Temu, AliExpress, TikTok Shop) have created entirely new cargo flow patterns, shipping low-value individual parcels directly from China-based factories to end consumers in Europe, the US, Southeast Asia, the Middle East, and elsewhere. The volumes are enormous: global parcel shipments are projected to exceed 236 billion in 2026, with China and broader Asia-Pacific accounting for roughly 60% of origin volumes.

Regional ASEAN e-commerce platforms (Shopee, Lazada, Tokopedia/Bukalapak, TikTok Shop SEA) generate intra-ASEAN parcel flows that are smaller in unit value but substantial in aggregate volume. These flows often move through regional integrators rather than dedicated freighters, but they shape the underlying demand for short-haul cargo capacity.

US-bound and Europe-bound e-commerce was the most affected by the 2025 trade policy changes. The removal of the US de minimis exemption made parcels under USD 800 from China and Hong Kong subject to standard tariffs and customs procedures, slowing the rapid growth of Shein and Temu shipments into the US market. The compensating shift was visible in cargo data: Europe-Asia flows grew sharply, intra-Asia flows strengthened, and US-Asia flows contracted. For network planners, this means the structural demand pattern is more complex than it was 18 months earlier, with shorter routes and intra-regional connections gaining share.

The fleet implication is that demand growth is now distributed more evenly across aircraft sizes. The traditional widebody-centric long-haul cargo model still dominates the trunk routes, but narrowbody freighters (737-800BCF, A321P2F) and turboprop freighters (ATR 72F, ATR 42F) increasingly fit the regional and intra-regional segments where parcel and small-shipment volumes are growing fastest.

5. The cross-border hub model

A specific commercial pattern that has emerged in the 2024-2026 period is the use of ASEAN hubs as transit points for cargo flows originating in southern China, with the goods routed through ASEAN before continuing to final destinations in Europe, the Middle East, or North America. The logic is partly geographic, partly regulatory, and partly commercial.

Geographically, Shenzhen, Guangzhou, and Hong Kong sit close enough to Singapore, Kuala Lumpur, and Jakarta that one short freighter leg can move large volumes of cargo to an ASEAN hub for onward distribution. The total transit time is competitive with direct long-haul service for many origin-destination pairs.

Regulatorily, ASEAN-based transit can offer benefits in customs treatment, duty exemption (through hub free commercial zones), and re-export classification that direct China-origin shipments may not receive. The KLIA Free Commercial Zone and similar facilities at Changi explicitly target this transit business.

Commercially, the ASEAN hub model lets the originating carrier (a Chinese freighter operator or an integrator) consolidate volume into manageable trunk-route services rather than operating direct services to dozens of final destinations. The JD Airlines Shenzhen-Singapore thrice-weekly service launched in 2025 is a clear example of this model in action.

The implication for ASEAN-based cargo operators is that the home-region hub strategy now needs to consider not just intra-ASEAN and ASEAN-to-elsewhere flows, but also the through-traffic dimension. A hub that captures Chinese-origin transit cargo earns handling and onward-flight revenues without requiring proportional growth in home-state passenger or domestic-cargo demand.

6. The regulatory layer

Cargo operations face a regulatory framework that overlaps with but differs from passenger operations in several important respects.

Chicago Convention Article 5 (covered in the previous post on charter vs scheduled operations) explicitly addresses cargo. Non-scheduled cargo flights enjoy the same baseline right of entry across contracting state territory as non-scheduled passenger flights, subject to the right of the territorial state to impose conditions. Scheduled cargo services, like scheduled passenger services, require Article 6 authorization through bilateral agreements.

ICAO Annex 18 (Safe Transport of Dangerous Goods by Air) governs the carriage of dangerous goods, which represents a substantial share of high-value air cargo (lithium batteries, pharmaceuticals, certain electronics, perishables requiring temperature-control). Operators carrying dangerous goods must satisfy specific training, packaging, documentation, and operational requirements that are more demanding than for general cargo. The pharmaceutical cool-chain segment is particularly significant in Singapore Changi’s growth story.

Bilateral cargo traffic rights are sometimes negotiated separately from passenger rights, particularly for fifth-freedom cargo operations (a carrier flying cargo between two foreign states via an intermediate point). The ASEAN MAAS framework (covered earlier in this series) provides multilateral coverage for intra-ASEAN scheduled cargo on broadly the same terms as passenger service, but extra-ASEAN cargo operations typically depend on bilateral arrangements.

Cargo ACMI arrangements (covered in the wet-lease/ACMI post) are extensively used in cargo markets, particularly for integrator operations and for managing capacity volatility on specific trade lanes. The structure of these arrangements (block-hour rates, minimum monthly utilisation, livery and crew configurations) follows the same principles as passenger ACMI but with cargo-specific operational requirements.

7. The fleet planning question

For an ASEAN regional carrier deciding whether and how to develop a cargo operation, several structural questions must be answered.

Will the operation rely on belly cargo capacity from the passenger fleet, or will the carrier acquire dedicated freighters? Belly-cargo operations are lower in marginal cost but constrained by the passenger network’s geography and frequency. Dedicated freighters provide independent network flexibility but require substantial fleet capital and operational infrastructure.

If freighters are added, which aircraft type? The 777F and 747-8F dominate widebody freight, the A330F/A330P2F is the medium-haul choice, the 737-800BCF and A321P2F address narrowbody segments, and the ATR 72F/42F serve niche regional cargo. The choice depends on the trade lanes served, the cargo profile, and the parallel passenger network.

What is the role of cargo in the network strategy? A flag carrier with substantial widebody passenger operations may add freighters as a complementary capacity layer (Thai Cargo model, with belly dominant and dedicated freighters supplementing). A LCC-oriented operator may stay belly-only or use wet-leased capacity for cargo surge periods. A specialist cargo subsidiary (Air Hong Kong, Cardig Air model) requires its own management infrastructure but enables focused commercial positioning.

How is the regional hub strategy structured? A carrier basing freighters in Singapore, Kuala Lumpur, or Jakarta inherits the existing hub infrastructure and connectivity advantages, but accepts the hub airport’s pricing and competitive environment. A carrier operating secondary hubs may face lower costs but lacks the network density needed for through-traffic.

8. Three rules for the cargo network planner

For carriers reviewing their cargo strategy, three working rules:

Rule 1: Match the cargo network model to the passenger network model. A hub-and-spoke passenger operation aligns naturally with a hub-and-spoke cargo operation, with belly capacity serving the same connecting flow logic. A point-to-point passenger operation can support point-to-point cargo at the same routes. Mismatched architectures (cargo network designed for one geography while passenger network serves another) typically lead to underutilised assets and operational complexity.

Rule 2: Treat express integrator flows as a distinct business segment. The express parcel and e-commerce integrator segment operates on schedule density, transit time, and reliability rather than on yield optimisation. Carriers serving this segment need to align their commercial terms and operational performance to integrator requirements, which can differ substantially from general cargo. The SIA-DHL partnership model is one approach; ACMI capacity provision is another; integrated freighter ownership is a third.

Rule 3: Plan for capacity volatility, not for steady-state demand. Cargo demand fluctuates with global trade conditions, e-commerce surges, supply chain disruptions, and geopolitical events. A network designed only for steady-state demand will struggle when conditions change. Building flexibility through wet-lease relationships, multi-modal capacity, and dynamic schedule adjustment is more important in cargo than in passenger operations.

Closing

Cargo operations in Southeast Asia have moved from the periphery to the centre of regional aviation strategy. The combination of growing intra-Asia trade, e-commerce expansion, semiconductor and AI-supply-chain flows, and the structural shift away from US-Asia toward Asia-Europe and intra-Asia traffic creates real opportunities for ASEAN-based operators that build cargo capability strategically. The hub investment patterns at Singapore Changi, the freighter fleet modernisation at Cathay Cargo and Air Hong Kong, the regional expansion intentions of MASkargo, and the growing presence of Chinese cross-border platforms together create a market environment that rewards carriers who think systematically about cargo network design.

The next article in this series will turn to a more operational topic: aircraft performance and hot-and-high operations in Southeast Asia, examining how the region’s geography and climate shape what aircraft can actually do at the airports where they fly.
