It's 2am here in LA so I am going to bed, but someone is free to paste the pictures directly into FT if you don't want to click on my blog -- over 60 pictures of the new lounge here:

Lounge is really nice and we should see Chicago UC-style food. No showers, but Polaris Lounge will be going into former IFL at LAX and will have showers.
Future Polaris lounges at hubs (except DEN and GUM) and eventually in Mainland China...many UA people, including Oscar, were hyping the Polaris lounge opening in ORD so my expectations are obviously very high for that one, because I thought the new LAX club is great.
