Been there 1.5 year ago and I actually don't remember that new terminal. We parked our aircraft on the GA apron and arrived (by Luxair bus ) in the "old" terminal wich I thought then could use a major overhaul. Must say that Luxembourg is one of the nicest airports to fly into. Long runway, nice surroundings, and ofcourse all the mighty heavies! And not too expensive (for a "major" airport).
