It follows the recent announcement that Etihad Airways would become airberlin's largest single shareholder.
Using an Airbus A330-200 aircraft, airberlin will operate four flights a week between Berlin and Abu Dhabi from Jan. 15.
Etihad Airways will place its EY code on these flights, providing European travelers with immediate access to a total of 29 flights a week to and through Abu Dhabi from four German hubs (Berlin, Düsseldorf, Frankfurt, Munich), with a plan to increase to 42 flights from mid-April.
Part of the new strategic partnership will see airberlin place its AB code on Etihad Airways flights from Düsseldorf, Frankfurt and Munich to Abu Dhabi and on Etihad Airways' flights from Abu Dhabi to Bangkok, Malé and Singapore.
Etihad Airways will in turn codeshare on airberlin flights to Basel, Berlin, Catania, Copenhagen, Hamburg, Hannover, Helsinki, Milan, Rome, Stuttgart, Venice and Zurich.
Additional codeshare destinations will be announced in the coming weeks, subject to government approvals.
Airberlin is Germany's second largest airline. The company has a workforce of 9,200 employees.
From its hub at Abu Dhabi International Airport, Etihad Airways serves 82 passenger and cargo destinations in the Middle East, Africa, Europe, Asia, Australia and North America.
