Air Berlin
former German airline
Air Berlin, branded as airberlin or airberlin.com was a major German airline. At its peak, it was Germany's second-largest airline, after Lufthansa, and Europe's tenth-largest airline in terms of passengers carried. It was headquartered in Berlin and had hubs at Berlin Tegel Airport and Düsseldorf Airport. At the time of its insolvency, it was a member of the Oneworld airline alliance, having joined in 2012.
The airline was originally founded by American interests in 1978 to provide airline service to West Berlin, a territory that could not legally be served by West German airlines such as Lufthansa due to political restrictions on East German airspace. In 1991, shortly after German reunification, Air Berlin became a German-owned company and shifted its core business to compete more directly with Lufthansa, eventually becoming one of Germany's biggest airlines. After years of losses, Air Berlin filed for insolvency in August 2017 and ceased operations two months later.
History
1978–1990: American charter airline in West Berlin
Originally registered as Air Berlin USA, the company was founded in 1978 as a wholly owned subsidiary of Lelco, an American agricultural enterprise headquartered in Oregon, to operate charter flights on behalf of German tour operators from Berlin Tegel Airport, mostly to Mediterranean holiday resorts.
The co-founders of Air Berlin USA were:
Kim Lundgren, a former Berlin-based flight engineer of Pan American World Airways;
John MacDonald, a former station manager of United States supplemental air carrier Saturn Airways at Berlin Tempelhof Airport in the 1960s and subsequent general manager Europe and vice president at the Berlin Tegel Airport base of the former United States supplemental carrier and charter airline Modern Air from 1968 until 1974;
Mort Beyer, Modern Air's executive vice president from 1967 until 1971 as well as the airline's president and vice president of the National Air Carrier Association in 1971 and founder of United States aviation consultancy Avmark.
Lelco was the agriculture business of Kim Lundgren's family in the United States.
This brief starts where responsible research should: with the source description of “Air Berlin” as former German airline. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as former German airline. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q156829. VIAF identifies the subject as 3545147270371635700000. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2012, 1978, 1991 and 2017.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
