エア・ベルリン
Air Berlin announced in 2008 that the trademark "LTU" would no longer be used. All flights were rebranded as Air Berlin. The last known flight under LTU callsign, but already in Air Berlin livery, was on 13 October 2009 from Montreal to Düsseldorf. As of April 2011, the AOC of LTU had been expired and the company itself was dissolved. On 27 October 2017, Air Berlin themselves ceased operations.
