Rising aviation fuel prices and tightening supplies of Jet A-1 are forcing Vietnamese airlines to revise flight plans, cut some routes and focus on key services.

Budget-carrier Vietjet Air said it has adjusted operations in line with guidance from the Civil Aviation Authority of Vietnam (CAAV) to maintain network stability. During April–May, including the peak April 30–May 1 holiday, the carrier will continue operating 64 international routes while adjusting frequencies on selected services to match demand.

National flag carrier Vietnam Airlines is prioritising routes with strategic importance for connectivity, trade, tourism and diplomacy. From April 1, 2026, the carrier plans to temporarily suspend several routes, including Hai Phong–Buon Ma Thuot, Hai Phong–Cam Ranh, Hai Phong–Phu Quoc, Hai Phong–Can Tho, Ho Chi Minh City–Van Don, Ho Chi Minh City–Rach Gia and Ho Chi Minh City–Dien Bien, affecting about 23 flights per week.

Bamboo Airways will concentrate on trunk routes such as Hanoi–Ho Chi Minh City–Da Nang and high-demand tourism destinations, while maintaining charter flights to China and the Philippines.

Vietravel Airlines, however,  plans to add a new aircraft in April and increase flights to key tourist destinations, while resuming the Hanoi–Bangkok route from April 24.

According to the CAAV, Jet A-1 prices have surged to over $220 per barrel from about $89 in February, significantly raising operating costs. Local airlines estimate expenses have risen by 20–30%.

Carriers are considering fare adjustments within regulatory caps and may introduce fuel surcharges on international routes from early April. They have also called for government support measures, including tax reductions and financial assistance.
