I understand that ladies travelling alone like the barbie because they have the option of the single seat thus taking away any risk of being trapped against the window by some smelly greasy perv with wandering mitts.
The cabin divider curtain was rather silly though and I am so glad that it has gone.
Only problem is the lack of locker space, but the vallet service is good when it works and the baggage handlers turn up. Having said that, when it has gone wrong, I have seen pilots climb into the hold to retrieve hand baggage. Bags delivered to the customer at the bottom of the steps by the captain! That's the BACX service.
