Fuel costs, which account for 35–40% of total operating expenses, have risen sharply in recent time, placing airlines under strain. According to the Ministry of Construction, operating costs have increased by 50–60% for Vietnam Airlines, around 30% for Sun Phu Quoc Airways, while VietJet Air has seen additional expenses of approximately 2 trillion VND (75.9 million USD) per month.

Meanwhile, MOPS Jet A-1 Singapore fuel prices now hover around 160 USD per barrel and are forecast to continue rising, potentially nearing 170 USD due to ongoing geopolitical tensions and constrained supply. The International Air Transport Association estimates that such increases could push airline operating costs up by 50–60%, and by over 70% if prices climb to 200 USD per barrel.
In addition to fuel volatility, conflicts in the Middle East have forced airlines to reroute flights to avoid restricted airspace, increasing flight times, fuel consumption, crew costs and maintenance expenses. Rising overflight charges and insurance premiums have further compounded operational costs.
Facing these pressures, airlines are implementing a range of adaptive measures. A representative of Vietnam Airlines said the carrier is drawing on fuel reserves while accelerating fuel-saving initiatives to sustain operations in the short term. However, if fuel prices approach 200 USD per barrel, airlines could face a scenario where “the more they fly, the greater the losses.”
To mitigate risks, Vietnamese carriers are restructuring flight schedules from April, prioritizing core domestic and strategic international routes while suspending less efficient services. At the same time, they are preparing to introduce fuel surcharges on international routes.
Globally, more than 60% of airlines have already implemented or are planning fare adjustments or fuel surcharges since mid-March, according to a survey by the Civil Aviation Authority of Vietnam (CAAV). Some carriers, including Air France, Thai Airways and United Airlines, have incorporated fuel costs directly into ticket prices, with increases typically ranging from 5 to 20%. Others, such as Malaysia Airlines and All Nippon Airways, have applied separate fuel surcharges, varying widely depending on distance and service class.
For air cargo, carriers like Lufthansa and Korean Air have also imposed fuel surcharges at 17,000 – 40,000 VND/kg, further affecting logistics costs.
Currently, Vietnamese airlines are formulating plans to introduce fuel surcharges on international routes, which may be implemented from early April.
According to agents and ticket offices, VietJet Air has announced adjustments to its fuel surcharge (YQ) for all direct international routes (excluding Japan and the Republic of Korea), as well as all connecting international itineraries, applicable to departing flights.
Regulators have emphasized the need for balanced solutions. Authorities are reviewing fare frameworks to ensure flexibility in response to fuel price fluctuations, while maintaining affordability for passengers and avoiding supply disruptions. CAAV has instructed airlines to optimize costs, safeguard cash flow, and maintain stable operations, particularly during peak travel periods.
