In terms of Band 1/2 then LUX (Luxair lounge) is perfectly functional but nothing special. Crémant, cold cuts of ham, salami, salmon and very rare beef (excellent), bread rolls and fruit salad. Bofferding on tap and Simon Pils in bottles. Sapphire free pour (not that that's an attraction, and occasionally it's Gordon's). Comfy chairs, good view. And lots of lime green chairs for some odd reason. Free WiFi (only a recent addition) and latrines inside the lounge. Functional, reasonably good, but not worth a trip to try out. Luxembourg's fairly nice though, and only 2EUR on the bus to the airport. Security is swift, at all times except Friday's 419.
