Long-thanh-airport-2026
The Ultimate 2026 Pillar Guide to Southeast Asia’s Most Ambitious Aviation Hub
For decades, travelers arriving in Ho Chi Minh City have known one airport: Tan Son Nhat. Crowded, congested, and bursting beyond its designed capacity, it has long been a bottleneck in Vietnam’s otherwise remarkable growth story. That story is about to change—dramatically. By the end of 2026, the first phase of Long Thanh International Airport will begin commercial operations, ushering in a new era for Vietnamese aviation. With a final planned capacity of 100 million passengers annually and a total investment exceeding $16 billion USD, Long Thanh is not merely an airport. It is a statement of intent—Vietnam’s declaration that it intends to compete with Singapore’s Changi, Bangkok’s Suvarnabhumi, and Kuala Lumpur’s International Airport for the title of Southeast Asia’s premier aviation hub.
By the end of this pillar guide, you will understand the phased opening roadmap, the strategic transfer of flights from Tan Son Nhat, the infrastructure that will make Long Thanh a world-class facility, and what this means for travelers, airlines, and Vietnam’s position in the global aviation landscape.
| Category | Quick Answer |
|---|---|
| Location | Long Thanh District, Dong Nai Province (40km east of Ho Chi Minh City) |
| Total Investment | Approximately 336,600 billion VND (~$16 billion USD) |
| Final Capacity | 100 million passengers/year + 5 million tons of cargo/year |
| Phases | 3 phases, with final completion by 2050 |
| Phase 1 Completion | Q3 2026 (construction) |
| Commercial Operations Start | December 1, 2026 |
| Phase 1 Capacity | 25 million passengers/year |
| Runways (Phase 1) | 1 runway (4,000m) |
| Terminal (Phase 1) | 1 terminal (373,000 m²) |
| Operator | Airports Corporation of Vietnam (ACV) |
| Management Consultant | Incheon International Airport Corporation (South Korea) |
Tan Son Nhat International Airport (SGN) was originally designed to handle 25 million passengers annually. In 2025, it handled nearly 40 million — operating at more than 150% of its designed capacity. The result is chronic congestion, taxiway gridlock, and a passenger experience that falls far short of Vietnam’s ambitions. The airport’s location—embedded within the dense urban fabric of Ho Chi Minh City—makes significant expansion impossible. Runways cannot be lengthened. Terminals cannot be expanded outward. Tan Son Nhat has simply run out of room.
While Vietnam has been constrained by infrastructure, its regional competitors have not stood still:
| Airport | 2025 Passenger Volume | Expansion Status |
|---|---|---|
| Singapore Changi (SIN) | ~70 million | Terminal 5 planned (50M capacity) |
| Bangkok Suvarnabhumi (BKK) | ~65 million | Satellite terminal opened 2024 |
| Kuala Lumpur International (KUL) | ~60 million | Ongoing expansion |
| Tan Son Nhat (SGN) | ~40 million (over capacity) | No expansion possible |
Without a new hub, Vietnam risks losing its competitive edge. Long Thanh is the answer.
Prime Minister’s Decision No. 648/QD-TTg explicitly directs the development of a “regional-level international air transport hub in the Ho Chi Minh City area”. The goal is to position Long Thanh not merely as a point-to-point airport, but as a true transit hub — where passengers from Europe, Northeast Asia, and Australia connect seamlessly to destinations across Southeast Asia and beyond. This is a deliberate challenge to the dominance of Changi and Suvarnabhumi, leveraging Vietnam’s central geographic position.

| Runways | 1 (4,000m x 75m) — capable of handling A380 |
| Terminal | 1 (373,000 m²) |
| Apron | 23 parking stands |
| Cargo Capacity | 1.2 million tons/year |
| Completion Date | Construction completed Q3 2026 |
| Commercial Start | December 1, 2026 |
| Component | Specification |
|---|---|
| Passenger Capacity | 50 million/year |
| Runways | 2 (second 4,000m runway) |

| Runways | 3 |
| Cargo Capacity | 5 million tons/year |
At full completion, Long Thanh will be one of the largest airports in Southeast Asia, comparable to Bangkok’s Suvarnabhumi and Singapore’s Changi in scale and ambition.
The Airports Corporation of Vietnam (ACV) has submitted a detailed two-step, three-phase transition plan outlining exactly how and when flights will move from Tan Son Nhat to Long Thanh.
Target: ~19% of international passenger volume. From the start of commercial operations until the end of the winter 2026 flight schedule, all long-haul international flights (including cargo) will be transferred from Tan Son Nhat to Long Thanh. This includes flights to Europe (Paris, Frankfurt, London, Moscow), North America, Australia/New Zealand, and all international cargo operations.
Why this matters for travelers: If you are flying long-haul to/from Ho Chi Minh City after December 1, 2026, you will almost certainly arrive at or depart from Long Thanh—not Tan Son Nhat. Plan ground transportation accordingly.
Target: Over 90% of international passenger volume by 2027. All remaining international flights will be transferred to Long Thanh—with one exception: short-haul routes under 1,000 km operated by Vietnamese airlines may remain at Tan Son Nhat temporarily (routes to Bangkok, Phnom Penh, Vientiane, etc.). The goal is to achieve over 90% of Ho Chi Minh City’s international passenger traffic at Long Thanh by the end of 2027.
Target: 100% of regular international flights. After 2030, all scheduled international flights will operate from Long Thanh. Tan Son Nhat will transition to a primarily domestic airport.
Before commercial operations begin, ACV will conduct three phases of operational testing in September, October, and November 2026, including simulated passenger flows, baggage handling trials, security drills, and airline familiarization flights. ACV has partnered with Incheon International Airport Corporation (South Korea) as a management consultant.
1. The Transfer Hesitation Risk: Of the 3.16 million connecting passengers at Tan Son Nhat in 2024, domestic airlines accounted for 95% of connecting traffic between domestic and international flights. These airlines are concerned about connection times, passenger unfamiliarity, and operational costs.
2. The Infrastructure Gap: The current road link—Ho Chi Minh City-Long Thanh-Dau Giay Expressway—is frequently congested. A transfer between the two airports could take 60-90 minutes during peak hours. ACV is working on dedicated shuttle buses and priority lanes.
3. Regional Competition Threat: ACV warns that if international routes are not concentrated at Long Thanh in a timely manner, Vietnam could face an 8.8% reduction in passenger output (over 2 million passengers per year) and an 8-9 year delay in passenger growth at Long Thanh.
| Flight Type | Arrival/Departure Airport (after Dec 1, 2026) | Notes |
|---|---|---|
| Long-haul international (Europe, US, Australia) | Long Thanh (new airport) | Plan 40-60 min transfer to Ho Chi Minh City |
| Short-haul international (Bangkok, Phnom Penh) | May remain at Tan Son Nhat temporarily | Check your ticket carefully |
| Domestic flights | Tan Son Nhat (existing airport) | Connections to Long Thanh require ground transfer |
| Option | Estimated Time | Estimated Cost |
|---|---|---|
| Private car/taxi | 45-60 minutes | $25-40 USD |
| Airport shuttle bus | 60-90 minutes | $5-10 USD |
| Future express rail | ~30 minutes (planned) | TBD |
Important note: If you have a connecting flight that requires transferring between Tan Son Nhat (domestic) and Long Thanh (international), allow at least 4-5 hours between flights during the initial transition period.
| Impact Area | Projection |
|---|---|
| Direct jobs (Phase 1) | ~15,000 |
| Indirect jobs | ~50,000+ |
| GDP contribution (annual) | ~$2-3 billion USD |
| Cargo handling (Phase 3) | 5 million tons/year |
The Long Thanh Airport City: Like Singapore’s Changi, Long Thanh is being developed as an aerotropolis—integrating logistics parks, free trade zones, hotels, convention centers, and residential developments. This transforms Long Thanh from a transportation node into an economic hub driving growth across Dong Nai Province and the southern economic region.
ACV has signed a consulting contract with the Incheon Airport consortium (Incheon International Airport Corporation and PIF Company). Incheon (Seoul) is consistently ranked among the world’s best airports. The partnership covers operational concepts, commercial policies, financial strategies, and operational testing. ACV has completed the first two phases of consulting, with Phase 3 currently underway.
| Date | Milestone |
|---|---|
| September-November 2026 | Operational testing phases at Long Thanh |
| December 1, 2026 | Commercial operations begin; long-haul international flights transfer |
| December 1, 2026 – March 27, 2027 | Winter 2026 schedule; ~19% of international traffic at Long Thanh |
| March 28, 2027 | Summer 2027 schedule begins; majority transfer accelerates |
| By end of 2027 | Over 90% of international traffic at Long Thanh |
| Post-2030 | All scheduled international flights at Long Thanh; Tan Son Nhat transitions to domestic focus |
Long Thanh International Airport is the most ambitious infrastructure project in Vietnam’s history—and one of the most significant in Southeast Asia. It represents a clear-eyed recognition that Vietnam’s economic aspirations cannot be fulfilled by an airport built in the 1920s and expanded haphazardly ever since. The transition roadmap, with its two steps and three phases, is carefully designed to balance operational reality with strategic ambition. The risks—airline hesitation, infrastructure gaps, regional competition—are real. But so is the opportunity.
By 2030, when all scheduled international flights have transferred to Long Thanh, Vietnam will possess a world-class aviation hub capable of competing with the best in Asia. By 2050, with a capacity of 100 million passengers annually, Long Thanh will have outgrown even today’s most optimistic projections.
For travelers, the message is clear: watch this space. By the end of 2026, your journey to Ho Chi Minh City will begin at a brand-new gateway—one designed not for the past, but for the future. Your next flight to Vietnam may land at a different airport. But your welcome will be just as warm.
