Not a LOT really. Lounge-wise (in Warsaw), there's a cramped section within the Polonez business lounge (right hand side as you walk past the first food counter, it has a dedicated entrance) which was (possibly still is, at least judging from the wording on the website) supposed to be for HON/SENs only yet all passengers holding a Star Alliance Gold card can access it so, it goes without saying, it may get fairly busy (as of not finding a seat) at times. That said, you will get escorted to the main terminal when arriving at a remote stand (which does happen 8 times out of 10) whereas, in regards to the blocked seat, I'm paging [MENTION=185918]hugolover[/MENTION] as he's the expert on this matter but it seems to me that LOT does seat blocking for all Star Alliance Gold members irregardless (I know this by direct experience especially when travelling with the Mrs who's also *G and, when booked on different PNRs, we never seem to be able to choose a seat next to each other).
