Four Fokker F27s joined the fleet in 1973 , enabling Biman to double the frequency of the Kolkata flight to a twice daily service . A Boeing 707 was added to the fleet in September and the flight to London became twice-weekly , while a Chittagong – Kolkata flight also began operating . In 1974 , operations were extended to Kathmandu ( February ) , Bangkok ( November ) and Dubai ( December ) . In 1976 , Biman sold two of its Fokker F27s and bought another Boeing 707 to extend international services to Abu Dhabi , Karachi and Mumbai . Singapore was added to Biman 's list of international destinations , when a third Boeing 707 was purchased in February 1977 , followed by Jeddah , Doha and Amsterdam the following year , which also saw the purchase of its fourth Boeing 707 . In 1977 , Biman was converted into a public sector corporation to be governed by a board of directors appointed by the government . The airline broke even for the first time in 1977 – 78 , and made a profit the following year . International destinations expanded to include Kuala Lumpur , Athens , Muscat and Tripoli in 1979 , followed by Yangon , Tokyo and Dhahran in 1980 . Biman took delivery of its first 85-seater Fokker F28-4000 in 1981 . In 1983 , three Douglas DC-10s joined the fleet and the airline started to phase out the Boeing 707s . The flight network expanded further to include Baghdad ( 1983 ) , Paris ( 1984 ) and Bahrain ( 1986 ) . On 5 August 1984 , Biman faced its worst accident ever when a Fokker F27 flying in from Chittagong crashed near Dhaka , killing all 49 on board . The long haul fleet was then supplemented by the purchase of two new Airbus A310s in 1996 , followed by the addition of two more in 2000 , from Singapore Airlines and Air Jamaica , and another in 2003
