Air Berlin, founded in 1978, was Germany’s second-largest airline until its bankruptcy in 2017. Operating primarily out of Berlin Tegel Airport, it expanded to become a significant player in European aviation. Air Berlin’s extensive route network covered destinations across Europe, North Africa, and the Americas. Despite facing financial struggles, it maintained a diverse fleet, including Airbus and Boeing aircraft. Its collapse led to significant disruptions in the European aviation market, with assets redistributed among competitors.
