Thanks for these recent LOT reports. I have a JFK-WAW-Asia trip on LOT coming up next year and was a bit worried - I was thinking of changing the flights to LH or LX if award space pops up. But maybe it won't be worth the effort.
JFK's terminal 7 has a bad reputation (although I've always liked it because it's small and manageable), so it's nice to hear that the lounge is decent.
