;Airlines never seem to get a happy medium to suit everybody's needs unfortunately. I prefer it to be a bit cooler myself but always see others wrapped in as many blankets as possible or with coats and jumpers on.
On on my BA flight the other night on an A321, I was sat directly behind J class. Had to take layers off because it was too hot. Went to the rear galley mid flight and from the emergency exit row onwards, there was a significant change in cabin temperature noticeable.
I have found CX the worst for keeping cabin temperatures on the higher side, but until now, have thought EK manage to keep the temperature quite ambient (for my liking anyway)
