Stumbled upon this the other day. A quick stroll through it reveals some useful, if at times brief and patchy reviews of various lounges. There are many more reviews of *A and independent lounges than there are of OW and Skyteam. In fact, OW is relatively sparsely represented. Anyway, just another resource that may assist somebody.

There is another lounge site which could assist some people. Haven't had much of a look at it yet.

I think they are both available for anyone to update/add lounges if they have the inclination.
