But you fail to mention they are reducing the number of PE seats on their 330, so not as successful as to what they were hoping.
At least to Australia reducing NOT removing. Seems the Middle East is the only area where it (W) doesn't attract passengers.
Given that the A330s are smaller than the 777s, I wondered why they decided to have the same number of seats in the W cabin...
The side issue in Australia is that the overall level of airfares (say compared to exUSA) is rather too high. I haven't checked recently but earlier this year when I did the W cabin PER -> USA was about AU$4500. USA--> PER something less than US$3000. Well the exchange rate altercations :shock

err alterations) seem to be on their way to fixing that though I don't see it hitting 1AU$ = $0.67US$. I suspect the standard Y fares will roughly match the percentages though exUSA the fares will be in "higher" Y fare classes.
Happy wandering
