True! I always travel with BA because they give me op-up's all the time- I have only ever experienced WT+ once, 3 times out of 4 they have upgraded me to CW! On the flight out I will be up to my neck in exam revision so a glass of champagne from CW would wash that down well- although my notes might deteriorate as the glass empties!
