Biman Bangladesh Airlines owes the Civil Aviation Authority of Bangladesh Tk5,842.91 crore, or about €408 million, making it by far the largest debtor among the country’s carriers. The outstanding bill, reported as of August 2026, is part of a sector-wide total that exceeds Tk7,000 crore and covers landing, navigation, counter-rental and other aviation charges, along with tax liabilities.
Biman accounts for roughly 83% of the amount owed to CAAB, with the debt spread across Dhaka’s Hazrat Shahjalal International Airport and airports in Chattogram and Sylhet. The unpaid balance includes about Tk3,452 crore tied to Dhaka, Tk1,781 crore in Chattogram and Tk603 crore in Sylhet, alongside roughly Tk512 crore in VAT and Tk53 lakh in income tax.
Other domestic airlines named in the reporting include GMG Airlines, Regent Airways, United Airways and Novoair. The arrears leave CAAB short of funds for airport operations and development, while one report linked the withheld revenue to projects such as runway expansion at Cox’s Bazar airport. Biman posted a profit in FY2024-25, but its overdue liabilities to CAAB and Padma Oil point to persistent cash-collection problems in Bangladesh’s aviation sector.
