Cabin Air
This thread reminds me that when I worked for Pan Am in the early 80's that the cabin crew used to complain about cabin air quality and would train each other up to check how many 'pax' systems were on when they went to the flight deck (tea, coffee or are you awake) - this was the time of the ozone scares. These were allegedly shut down to save fuel. I wonder how many airlines are reducing air conditioning today to save fuel ?? (cough, gasp, splutter)....
