Very OT: Received today the letter offering keeping up the Senator card for "mere" €2000 for the next year, since I did not meet their expectations despite all my efforts. I think, I will settle for the FTL-card after 03/2013... Senator lounges in Germany are without a doubt the benefit I will be missing. But not worth two grands!
To put the offer in context, that is roughly the price for one longhaul. How many points were you short of SEN ? I mean if you only were short one LH C, then the offer seems very bad. If you were short several trips, then is is better.
