After a series of name changes, originally founded in 1992 as Deutsche BA, Dba or Fly-dba, was taken over by Air-Berlin in 2007.
On 27Aug06 Air-Berlin announced the takeover of Dba, but the brand was to remain in operation until April 2007, when the company would dissolve into Air-Berlin.
By that time, investors (Intro Verwaltungs Investment Group) which had a share in Dba also had a share in LTU; the strategy was that LTU would concentrate on long-haul operations, while Dba would do short-haul operations. LTU was also taken over by Air-Berlin, as announced in March 2007.
