I've read a few reviews of the A330 that the cabin temperature is often kept uncomfortably high. We're on an overnight from EWR-ZRH coming up, and (she doesn't read this, thankfully) will be traveling with a menopausal wife. We typically fly UA and it's perfectly fine, but if we get a hot cabin (in J, if that matters) she's going to be miserable. Actually to the point where she asked me to look for other options if it's going to be hot.

So my questions are.... Is it really that much different than USA carriers? If it is, do FA react and act on requests from passengers to lower the temp if asked? What is the actual temp if it is considered "warm"? I have a temp gauge on my watch, and am always curious on flights. Most of my overnight UA flights live anywhere between 68-71* F.
