Having just stepped off what I swear will be my last Qantas flight ever (ex-SYD leg was above average save for the use of a domestic-configured 767 but the ex-AKL sector was appalling with the same domestic 767 and crew who made me feel like I'd intruded on a funeral with the countenance to match - not one smile during the whole flight and a cabin services director who was more incompetent than Bush at grammar), those Air NZ A320s are looking even more attractive than ever - even with a 42" pitch in J, which couldn't possibly be worse than whatever miserly seat pitch is fitted on those QF domestic ZX* series.
The question: is cabin separation enforced on the Air NZ A320? The reason I ask is mainly a bathroom issue - from my understanding of the 320 there is one bathroom forward and two bathrooms at the back - so, as Air NZ have advertised on their website, 2 for the Y pax and the front one for the 8 J pax. Does this work in practice? On the BA Airbuses the Y pax often go forward to use the front bathroom, and I wouldn't be too happy to see that on NZ.
