airberlin topbonus - Air Berlin Top Bonus Silver/Gold Qualification

Hi-

Been trying to find the terms and conditions of Air Berlin's Top Bonus Program.

Can anyone provide me with a link or some info as of when you attain silver/gold status and what their qualification cycle is?

Your input is much appreciated.

PS Any word on whether AB will set up any lounges or the likes in the near future?

There has been some basic attempt at a lounge at TXL.

Ahh yes- thank you.
