Club 2000 VIPs have lots of small attentions, like I once saw a FA come and update a member in the Berlin AF lounge about the flight to CDG. WHenever there's a Club 2000 onboard, the pruser greets him/her by name.

AF Central seem to pick their Club 2000 members (and maybe it's for life), but they also grant their local affiliates some cards that go as a gift but may not last forever...

I was told that Club 2000 members rarely travel (they're the ones who decide for others'flights though), maybe that's why they're so well treated...
