October 11, 2016: Can someone please tell me why it’s always cold in an airplane cabin? I understand that flying to Europe and beyond over the North Atlantic — with outside temperatures usually minus 60 to 70 degrees and countries like Iceland and Greenland still masses of ice covered landscape — why is the inside cabin temperature is always cold too? That is until 30 minutes or so before landing and then it warms up. Is cabin temperature control the tool of the flight crew to punish travelers? Overcrowding, poor service, middle seat discomfort, cold coffee, isn’t enough punishment? With most airlines now having individual seat power connections, I wonder if we could ask for our own space heater? Seems only proper!
