Do you find that the airplane cabin are often very warm? I have often taken overnight First Class in the nose or upper deck and Business Class on the main deck and upper deck and I sleep a lot and the cabin becomes very warm and hot, not humid but a hot hot. I have asked them to turn it down, but no one else seems to complain and the temperature never seems to go down. When I fly on the upper deck next to the doors it is too cold. Does anyone else find this true?
