Bamboo Airways is now operating just three aircraft, a sharp decline from its previous fleet, according to the latest data from German aviation database Planespotters.
The database shows that nine Vietnamese airlines currently own aircraft. Vietjet Air has the country's largest fleet with 107 aircraft, followed by Vietnam Airlines with 97.
New entrant Sun PhuQuoc Airways ranks third despite only recently launching operations, with a fleet of 16 aircraft.
Planespotters, which is based in Germany, provides detailed information on aircraft fleets and the operational history of individual aircraft worldwide.
Bamboo Airways, formerly controlled by businessman Trinh Van Quyet, once operated a fleet of 44 aircraft, including Airbus A319, A320, A321 and Boeing 787-9 Dreamliner jets. The reduction comes as the airline continues to face financial pressure.
The carrier recently announced adjustments to its flight schedule, apologised to affected passengers and confirmed that ticket refunds would be provided. It said its customer service centre would process refund requests in the order they were received, although handling times could be longer than usual because of increased demand.
Vietnam's aviation market continues to attract strong investor interest. In its Commercial Market Outlook, Boeing identified Vietnam as one of the fastest-growing aviation markets in the region.
According to the Civil Aviation Authority of Vietnam, the country's aviation sector carried 45.49 million passengers and 813,200 tonnes of cargo during the first six months of the year, representing increases of 9.8 per cent and 16.4 per cent, respectively, compared with the same period in 2025.
The market has recently seen the entry of new private-sector operators, including Sun PhuQuoc Airways and Crystal Bay, alongside Bamboo Airways' efforts to rebuild its business. Industry observers say Vietnam's aviation sector is returning to the rapid growth seen before the Covid-19 pandemic, supported by an expected 24 million international visitors this year.
Against that backdrop, airlines are accelerating fleet expansion plans. Earlier this year, Vietjet Air announced the delivery of more than 20 new aircraft in less than a month, the largest fleet expansion in the low-cost carrier's history.
Sun PhuQuoc Airways plans to expand its fleet to 20 aircraft this year and 35 aircraft by 2027. Vietravel Airlines, following its acquisition by T&T Group, is pursuing a target fleet of 30 aircraft while preparing to rebrand. Meanwhile, Vietnam Airlines is advancing plans to invest in 50 narrow-body aircraft.
Bamboo Airways said in March that it aims to rebuild its fleet to 40 aircraft in the coming years.
