On 30 December 2015, the administrative court in Braunschweig ruled in favour of the German civil aviation authority (the Luftfahrt-Bundesamt) and against Air Berlin regarding some of their codeshare operations with Etihad Airways. The shared sale and advertising of 31 out of 83 routes which were marketed by both were declared illegal and ordered stopped by 15 January 2016 as they were not covered by the bilateral air-traffic agreement between Germany and the UAE. The Luftfahrt-Bundesamt had allowed these flights until a definite legal ruling was made.
