The civil aviation ministry has found several Biman officials, including high-ups, fully responsible for the syndicate that artificially hiked the prices of flight tickets to Malaysia in May this year.

Biman Bangladesh Airlines has seen a sharp rise in ticket sales which the aviation ministry claims was due to a drive against corruption in ticketing.

A syndicate in Biman had been blocking the sale of tickets online and channeling those to the black market with the help of some unscrupulous travel agents, a civil aviation ministry probe revealed.
