Regarding the previous two posts:

Re#1: My understanding is that Garuda will join Skyteam some time in 2012 (which would be "by 2012" in my understanding). So you will probably not have lounge access in December. Sorry mate for being the bearer of bad news.

Re#2:
(a) Membership in Skyteam is always "fully-fledged" (at least nowadays). So you will definitely earn EQMs on all flights with which you can earn miles.
(b) Whether cheap fares might not give you miles at all (or only at a reduced rate) is a matter of (individual) negotiation between your FFP and the new Skyteam airline, and this is independent of Skyteam membership.
(c) Finally, even in those days when a reduced type of Skyteam membership existed, you would still earn EQMs on all flights that gave you miles.
