Air Berlin, which is headquartered in Berlin, is Germany’s second largest airline in terms of passengers. At the time of its founding in 1978, it was headquartered in Miami, Florida, for legal reasons regarding post World War II regulation of air traffic in and out of Berlin.
The airline joined the Oneworld alliance in 2012, and I first travelled with them in June 2013, on a Boeing 737-700 out of their home base at Tegel.
Tegel was the second airport I used in Berlin. My first visit was in June 2013, at which time TXL was the busiest airport serving the German capital.
Tegel, named for the locality in the north-west of the city where it is situated, is the main hub of Air Berlin, which I also flew for the first time from here. The airport will have been part of aviation history for more than a hundred years when it closes after Berlin’s “new” Brandenburg airport finally opens.
