When I was flying out of DUS with AB on BA Bronze last week, I had a chance to check out AB's "exclusive waiting area" that is open for OW Ruby and above cardholders.

After scanning my boarding pass at an automated entrance gate, I was greeted by a nice enclosed area with about 10 tables, comfy chairs, greenery, newspapers and all-you-can-drink free soda & water bottles from a "robot arm vending machine".

Of course the whole thing is very barebones compared to normal lounges, but for someone traveling on lowly Ruby, it was nice perk to have a quiet area away from the unwashed masses

Is this AB DUS only or have I just not looked hard enough at other airports?

Cheers!
