I think the value of the WT+ product depends entirely on how you are used to travelling.
My daughter+boyfriend returned from JFK a few days ago in WT+.
Boyfriend (used to travelling in Y on dodgy airlines) - "Wow, that was so comfortable, we had so much space, tons of legroom, the movies were great, the food was yum, and the crew were really brilliant".
Daughter (used to travelling in CW and F with daddy) - "That was hell, worst flight of my life, I feel like sh$t".
