You may want to avoid travelling on Bangladesh’s state carrier, Biman Bangladesh Airlines. The airline is planning to cut down on the frequency of flights to international destinations because it cannot pay for the repair of five of its fleet of 13 aircraft. Five out of Biman's 13 aircraft are now out of service due to mechanical faults and routine maintenance. Besides lack of aircraft, Biman was losing money because of high operational costs, including soaring fuel prices, and poor management. The airline has been unable to pay for aviation fuels.
