If you do a search you will find other threads about this. In my experience Club Class is good - considering the price difference with international J -. I don't think it can be called business class and I strongly disagree with other users who have said in other threads that it is much like BA-WT+ or UA-E+. I think this would be a nice alternative for the middle-class in a three-class aircraft (still as a premium economy product, again I am not saying this is business class) but I guess there is no economic justification for it.

IMO, definitely worth the price, specially during summer with more-than-full aircrafts.
