Air Berlin

Air Berlin was Germany's second-largest airline and one of Europe's major low-cost and leisure carriers. Founded in 1978 and headquartered in Berlin, Germany, the airline operated scheduled and charter flights across Europe, North America, and the Middle East, serving tens of millions of passengers annually at its peak. The airline underwent significant transformation over the decades, shifting from a charter operator to a hybrid carrier offering both low-cost and full-service products. It joined the oneworld alliance in 2012, expanding its global reach and codeshare partnerships, particularly with Etihad Airways, which became a major shareholder. Facing mounting financial losses and operational challenges, Air Berlin filed for insolvency in August 2017 after Etihad Airways withdrew further funding. The airline ceased operations on October 27, 2017. Its routes and aircraft were subsequently absorbed by competitors including Lufthansa and easyJet.
