Vietnam Aligns with Thailand as Higher Airfares Put Holiday Plans at Risk Amid Fuel Costs and Capacity Crunch

The rebirth of tourism in Southeast Asia is facing a strong headwind. Most of the nations of the region are pursuing transnational policies, including a Schengen-like visa policy. Yet, rising prices are affecting the ability of people to travel. Rising prices for aviation fuel means that airlines charge more for tickets and flying becomes less. This creates a situation where there are insufficient seats on planes for the demand and people are unable to travel to their destinations. Civil Aviation authorities in the region are trying to lower prices. If Vietnam and Thailand cooperate in tourism and transport, they need adequate means of transport and need to be able to carry all the expected travelers.

The Rise of Southeast Asian Tourism and Regional Alignment

As of late September 2026, the global tourism industry continues to view Southeast Asia as a primary engine for post-pandemic travel recovery. Having successfully moved past the border closures of previous years, nations across the Association of Southeast Asian Nations (ASEAN) have pivoted from individual recovery strategies toward highly integrated regional cooperation. Recognising that modern international travellers increasingly favour multi-destination itineraries, governments are tearing down bureaucratic barriers to stimulate long-stay tourism. At the forefront of this movement are Vietnam and Thailand—two tourism powerhouses that have historically competed for the same demographic of international arrivals but are now choosing synergy over rivalry.

The rationale behind this strategic pivot is firmly rooted in economics. According to data from the Vietnam National Authority of Tourism (VNAT) and the Tourism Authority of Thailand (TAT), international visitors who travel across multiple borders tend to spend significantly more time and money within the region. However, despite these sweeping diplomatic ambitions and heavily funded joint marketing campaigns, a stark macroeconomic reality has emerged. Supply-chain deficiencies within the commercial aviation sector have begun to unravel optimistic arrival forecasts. While forward-thinking policy alignments seek to eliminate invisible borders, severe physical transport barriers are mounting at an alarming rate.

For everyday travellers and the hospitality sector alike, the immediate consequences are highly visible and deeply concerning. Rising operational costs within the aviation industry have created an environment where higher airfares put holiday plans at risk, presenting a systemic challenge that regional authorities must collaboratively address. Without robust, affordable air connectivity, the most innovative visa policies and cross-border tourism campaigns risk falling flat, unable to reach their projected economic potential.

Six Countries, One Destination: The Schengen-Style Ambition

The centrepiece of this new era of regional alignment is the ambitious “Six Countries, One Destination” initiative. First formally championed by Thai Prime Minister Paetongtarn Shinawatra and endorsed by Vietnamese Prime Minister Pham Minh Chinh on the sidelines of major diplomatic summits, this proposed visa framework aims to replicate the seamless border crossings of Europe’s Schengen Area.

Diplomatic Progress and Bilateral Agreements

The initiative officially encompasses six neighbouring countries: Thailand, Malaysia, Singapore, Vietnam, Laos, and Cambodia. By implementing a single, unified visa, tourists from lucrative long-haul markets—such as North America, Europe, and the Middle East—could easily traverse mainland Southeast Asia without the logistical nightmare of securing multiple individual visas. The alignment between Vietnam and Thailand is particularly critical, as they serve as the primary aviation gateways for the entire bloc.

To support this mechanism, TAT and VNAT have begun drafting joint hospitality and dining packages, highlighting cross-border culinary tours featuring Michelin-rated establishments, heritage site circuits, and unified promotional branding. Yet, industry leaders note that creating a shared visa zone will inevitably intensify internal competition. Destinations with superior infrastructure and affordable connectivity will absorb the lion’s share of visitors, leaving less prepared regions behind. This competitive pressure places immense importance on domestic aviation capability, an area currently fraught with crisis.

The Aviation Capacity Crunch: A Critical Stumbling Block

Even as diplomatic channels celebrate the progress of the single-visa initiative, the mechanics of getting tourists from one destination to another are breaking down. The commercial aviation sector in Southeast Asia is currently navigating one of its most severe capacity crunches in modern history. An unprecedented shortage of operational commercial aircraft has drastically reduced the supply of available seats, sending shockwaves through the pricing algorithms of major carriers.

When seat supply plummets while travel demand remains robust, the inevitable result is a sharp inflationary spike in ticket prices. It is precisely this dynamic where higher airfares put holiday plans at risk for the budget-conscious leisure traveller. Families planning year-end holidays, backpackers relying on low-cost carriers, and corporate travellers are all feeling the financial squeeze.

The Pratt & Whitney Engine Crisis and Fleet Groundings

This capacity crunch is not a symptom of poor airline management, but rather a direct consequence of a severe global mechanical and supply-chain breakdown. A significant portion of the crisis stems from mandatory global maintenance and availability constraints surrounding Pratt & Whitney Geared Turbofan (GTF) engines. These engines, heralded for their fuel efficiency, are widely used on the Airbus A321neo—a vital workhorse aircraft for short-to-medium-haul routes across ASEAN.

Vietnam’s aviation sector has been disproportionately battered by this issue. According to official figures released by the Civil Aviation Authority of Vietnam (CAAV) extending from late 2025 into 2026, 28 commercial aircraft were grounded in Vietnam due to these engine shortages. The grounded fleet included 24 Airbus A321neos, three Airbus A350s, and one Airbus A320ceo. At the height of the groundings, this represented over 13 per cent of the nation’s entire domestic fleet. Maintenance queues for these engines stretch for months, meaning airlines cannot simply cycle their aircraft back into service, leading to prolonged schedule disruptions and cancelled routes.

Surging Jet A-1 Fuel Prices: The Economic Squeeze on Carriers

Compounding the crisis of grounded fleets is the skyrocketing cost of aviation fuel. Jet A-1 fuel economics remains one of the most volatile and impactful components of airline profitability, typically accounting for 30 to 40 per cent of an airline’s total operating expenses. Throughout early to mid-2026, geopolitical uncertainties and constrained global refining capacities pushed aviation fuel prices to restrictive new highs.

Airfare Surges and Airline Network Adjustments

For countries like Vietnam and Thailand, which heavily rely on imported refined petroleum products, global price surges instantly translate into domestic inflation. The Ministry of Transport in Vietnam and various market analyses noted that domestic airfares soared by 15 to 20 per cent as a direct reaction to the fuel crunch.

To protect their precarious profit margins, airlines were forced to undertake aggressive network adjustments. By the second quarter of 2026, carriers like Pacific Airlines reduced their operational capacity by 8 to 30 per cent, entirely cutting flights on off-peak days and abandoning low-efficiency time slots. While these corporate decisions successfully mitigated financial haemorrhaging for the airlines, they effectively stranded consumers. With fewer flights operating and those remaining priced at a premium, local and international tourists are being priced out of the market.

Official Developments from the Civil Aviation Authority of Vietnam (CAAV)

To maintain order within the turbulent aviation market, the Civil Aviation Authority of Vietnam (CAAV) has been issuing regular directives and statistical updates. Remarkably, despite the supply-side constraints, consumer demand has not abated. CAAV data revealed that in the first quarter of 2026 alone, the air transport market accommodated 24.19 million passengers, representing a staggering 16.4 per cent year-on-year increase.

This surge in passenger volume against a backdrop of shrinking fleet sizes illustrates a classic economic bottleneck. To optimise efficiency, the CAAV officially sanctioned network adjustments across Vietnamese airlines starting in April 2026, permitting carriers to scale back non-profitable routes to cope with Jet A-1 fuel prices. While this regulatory flexibility prevented airline insolvencies, it explicitly endorsed a higher-yield, lower-volume operational model. Consequently, cheap promotional fares have largely vanished from the market, structurally transforming the demographics of who can afford to fly domestically.

Thailand’s Capacity Crunch: Slower Growth in Passenger Supply

The aviation malaise is not isolated to Vietnam. Thailand, acting as the primary aviation hub for the proposed “Six Countries, One Destination” initiative, is fighting an identical battle. Official statistics from the Civil Aviation Authority of Thailand (CAAT) and international aviation bodies like OAG highlight that Thailand, alongside Malaysia and the Philippines, posted some of the steepest declines in regional seat capacity as airlines frantically adjusted schedules to cope with higher jet fuel costs.

The Response from the Tourism Authority of Thailand (TAT)

The Tourism Authority of Thailand (TAT) has officially acknowledged that exorbitant flight prices are suppressing potential tourist numbers. To counter this, TAT has pivoted its marketing strategy away from mass-volume tourism toward higher-yield segments. This involves promoting longer stays, high-end wellness retreats, and luxury culinary experiences that justify the steep initial transport costs.

However, this strategy inherently excludes the budget backpackers and middle-class families that historically formed the backbone of Southeast Asia’s tourism boom. Both Thailand and Vietnam recognise that if higher airfares put holiday plans at risk for the middle class, the volume required to sustain the massive hospitality infrastructure built over the last decade will simply not materialise.

Economic and Policy Implications for the ASEAN Bloc

The intersection of ambitious tourism policies and restrictive aviation economics carries profound implications for the ASEAN bloc. Economically, tourism is a major contributor to the Gross Domestic Product (GDP) of both Thailand and Vietnam, directly supporting millions of jobs in accommodation, retail, food services, and transport.

From a policy perspective, the current crisis highlights a critical disconnect between ministries of tourism and ministries of transport. While tourism boards aggressively promote open borders and increased footfall, aviation authorities are forced to ration flight slots and approve fare hikes. To resolve this paradox, cohesive government intervention is required. Official discussions have surfaced regarding the potential for subsidising landing fees, providing tax rebates on aviation fuel for domestic carriers, and temporarily easing regulations on wet-leasing foreign aircraft to plug the capacity gap.

Furthermore, international organisations such as the International Air Transport Association (IATA) and UN Tourism have continuously urged governments to view aviation not as a luxury sector to be heavily taxed, but as a core piece of public utility infrastructure. High aviation taxes and passenger service charges, when stacked on top of surging base fares, create an insurmountable barrier for budget travellers.

Tourism, Business, and Public Impact: Navigating High Connectivity Costs

The tangible impact of the capacity crunch extends far beyond cancelled family holidays; it strikes at the heart of domestic and bilateral commerce. Small and medium-sized enterprises (SMEs) operating in provincial tourist hotspots—such as Da Nang and Phu Quoc in Vietnam, or Chiang Mai and Phuket in Thailand—are reporting noticeable drops in domestic weekend footfall. When domestic airfares rise by 20 per cent, local tourists often opt for terrestrial travel, or cancel their plans entirely.

For the business community, the lack of affordable, frequent flights stifles corporate mobility. Vietnam and Thailand are deep in the process of expanding their bilateral trade, encompassing smart agriculture, digital technology, and green manufacturing. A reduction in flight frequencies between business capitals like Ho Chi Minh City and Bangkok forces executives into longer, more expensive travel arrangements, indirectly acting as a tax on cross-border trade.

The public sentiment is increasingly vocal. Consumer protection agencies have monitored a sharp rise in complaints regarding sudden flight cancellations, rescheduled itineraries, and opaque pricing algorithms. While airlines cite global engine shortages and fuel spikes as valid force majeure events, the everyday consumer bears the ultimate frustration and financial loss.

Strategic Countermeasures: How Governments Can Mitigate the Crisis

Addressing a crisis rooted in global supply chains requires pragmatic, multifaceted domestic countermeasures. Both the Vietnamese and Thai governments are actively exploring mechanisms to alleviate the pressure on airlines and passengers alike.

Firstly, regulatory bodies are expediting the approval processes for airlines seeking to dry-lease or wet-lease additional aircraft from international lessors. By circumventing the backlog of Pratt & Whitney engine repairs, airlines can temporarily boost their fleet sizes, restoring some equilibrium to seat supply.

Secondly, ministries of finance are under pressure to review the taxation structures applied to Jet A-1 fuel. Temporary suspensions of environmental levies or import tariffs on aviation fuel could instantly lower operational overheads for airlines, provided that regulatory bodies enforce a subsequent reduction in consumer ticket prices.

Finally, long-term investments in high-speed rail networks are gaining unprecedented political traction. If domestic travellers have viable, affordable rail alternatives for short-haul intercity journeys, airlines can reallocate their limited aircraft to highly profitable international routes, supporting the influx of foreign tourists generated by the single-visa initiative.

Future Outlook: Ensuring Seamless Travel Beyond 2026

Despite the immediate turbulence, the long-term outlook for the Vietnam-Thailand tourism alignment remains cautiously optimistic. Both nations are fundamentally committed to transforming Southeast Asia into the world’s most interconnected and vibrant tourism bloc.

Long Thanh International Airport: A Beacon of Future Capacity

A crucial element of Vietnam’s strategy to overcome aviation bottlenecks is the massive infrastructural investment in Long Thanh International Airport. Managed by the Airports Corporation of Vietnam (ACV), construction of this mega-hub is accelerating to meet a completion target for the third quarter of 2026, with commercial operations slated for the fourth quarter.

Once operational, Long Thanh will dramatically expand Vietnam’s international landing capacity, alleviating the chronic congestion currently plaguing Ho Chi Minh City’s Tan Son Nhat Airport. However, official reports warn of a severe workforce shortfall of nearly 6,000 construction workers, which authorities must immediately address to prevent operational delays.

In conclusion, the vision of a borderless Southeast Asian tourism zone is tantalisingly close. However, until the global aviation supply chain stabilises and regional governments implement robust transport economic safeguards, the reality of high ticket prices will remain a major hurdle. The success of the “Six Countries, One Destination” initiative relies not just on the stroke of a diplomatic pen, but on the tangible ability of airlines to put affordable planes in the sky.

The Air Travel Bubble (ATB) marks a significant development in air travel within Southeast Asia. However, the current state of air travel still poses a major constraint to the realization of the single ASEAN visa. Finding ways to alleviate costs, for example, through aviation tax exemptions, is crucial to promoting sustainable tourism. The ongoing engine shortage and increase in Jet A-1 fuel prices must also be considered. Transportation infrastructure affects a country’s tourism potential and, therefore, integration of transport economics with tourism policies should improve the position of Southeast Asia in the global tourism landscape.
