Having said that I rode on a VS A340
once that was so cold I could see my
breath
OOhhh, lovely
Our bunch insist that we fly around with a minimum of 25 degs and often we'll be asked to turn it a bit more. It seems that Asians are cold blooded and anything below that temp they'll start to freeze. It's absolutely ridiculous when you're in the cabin, it's hotter than Hades and the cabin crew come around offering blankets. If you're at the back of the aircraft then you won't get offered a blanket because they've all been taken.
Hand-in-hand with that goes the number of requests for seats etc to be cleaned because of vomit. Believe me, more than I ever had in previous airlines where the absolute max was 23 degs.
