For lounge access you need OW sapphire (BA Silver)

As you are in EU BA is as good as any. AA is the other default choice, but AA status will not get you AA domestic lounge access. Look at the links in post 2
However there are posts that Air Berlin will/can do a status match.

Note AA, BA & QF require 4 off AA/BA/QF flights respectively before status. No idea if AB have this 4 segment requirement
