In future, Air Berlin and Iberia are offering selected flights under joint flight numbers.
The connection possibilities from and to Madrid will improve for Air Berlin passengers as a result of the agreement. Iberia in turn will benefit from the extensive domestic route network and the good connections to destinations in Germany and Scandinavia via the Air Berlin hub in Berlin.
In a further step, plans are underway to expand the codeshare agreement to the frequent flyer programs of both airlines, Air Berlinâ€˜s topbonus as well as Iberia’s plus.
